Historical Commentaries

Scholarly Analysis and Interpretation.

For the word of God is quick, or living, etc. What he says here of the efficacy or power of the word, he says it, that they might know, that it could not be despised with impunity, as though he had said, "Whenever the Lord addresses us by his word, he deals seriously with us, in order that he may touch all our inmost thoughts and feelings; and so there is no part of our soul which ought not to be roused." [1] But before we proceed further, we must inquire whether the Apostle speaks of the effect of the word generally, or refers only to the faithful. It indeed appears evident, that the word of God is not equally efficacious in all. For in the elect it exerts its own power, when humbled by a true knowledge of themselves, they flee to the grace of Christ; and this is never the case, except when it penetrates into the innermost heart. For hypocrisy must be sifted, which has marvelous and extremely winding recesses in the hearts of men; and then we must not be slightly pricked or torn, but be thoroughly wounded, that being prostrate under a sense of eternal death, we may be taught to die to ourselves. In short, we shall never be renewed in the whole mind, which Paul requires, (Ephesians 4:23,) until our old man be slain by the edge of the spiritual sword. Hence Paul says in another place, (Philippians 2:17,) that the faithful are offered as a sacrifice to God by the Gospel; for they cannot otherwise be brought to obey God than by having, as it were, their own will slain; nor can they otherwise receive the light of God's wisdom, than by having the wisdom of the flesh destroyed. Nothing of this kind is found in the reprobate; for they either carelessly disregard God speaking to them, and thus mock him, or clamour against his truth, and obstinately resist it. In short, as the word of God is a hammer, so they have a heart like the anvil, so that its hardness repels its strokes, however powerful they may be. The word of God, then, is far from being so efficacious towards them as to penetrate into them to the dividing of the soul and the spirit. Hence it appears, that this its character is to be confined to the faithful only, as they alone are thus searched to the quick. The context, however, shows that there is here a general truth, and which extends also to the reprobate themselves; for though they are not softened, but set up a brazen and an iron heart against God's word, yet they must necessarily be restrained by their own guilt. They indeed laugh, but it is a sardonic laugh; for they inwardly feel that they are, as it were, slain; they make evasions in various ways, so as not to come before God's tribunal; but though unwilling, they are yet dragged there by this very word which they arrogantly deride; so that they may be fitly compared to furious dogs, which bite and claw the chain by which they are bound, and yet can do nothing, as they still remain fast bound. And further, though this effect of the word may not appear immediately as it were on the first day, yet it will be found at length by the event, that it has not been preached to any one in vain. General no doubt is what Christ declares, when he says, When the Spirit shall come, he will convince the world, (John 16:8 9.) for the Spirit exercises this office by the preaching, of the Gospel. And lastly, though the word of God does not always exert its power on man, yet it has it in a manner included in itself. And the Apostle speaks here of its character and proper office for this end only, -- that we may know that our consciences are summoned as guilty before God's tribunal as soon as it sounds in our ears, as though he had said, "If any one thinks that the air is beaten by an empty sound when the word of God is preached, he is greatly mistaken; for it is a living thing and full of hidden power, which leaves nothing in man untouched." The sum of the whole then is this, -- that as soon as God opens his sacred mouth, all our faculties ought to be open to receive his word; for he would not have his word scattered in vain, so as to disappear or to fall neglected on the ground, but he would have it effectually to constrain the consciences of men, so as to bring them under his authority; and that he has put power in his word for this purpose, that it may scrutinize all the parts of the soul, search the thoughts, discern the affections, and in a word show itself to be the judge. But here a new question arises, "Is this word to be understood of the Law or of the Gospel?" Those who think that the Apostle speaks of the Law bring these testimonies of Paul, -- that it is the ministration of death, (2-Corinthians 3:6, 7,) that it is the letter which killeth, that it worketh nothing but wrath, (Romans 4:15,) and similar passages. But here the Apostle points out also its different effects; for, as we have said, there is a certain vivifying killing of the soul, which is effected by the Gospel. Let us then know that the Apostle speaks generally of the truth of God, when he says, that it is living and efficacious. So Paul testifies, when he declares, that by his preaching there went forth an odor of death unto death to the unbelieving, but of life unto life to believers, (2-Corinthians 2:16,) so that God never speaks in vain; he draws some to salvation, others he drives into ruin. This is the power of binding and loosing which the Lord conferred on his Apostles. (Matthew 18:18.) And, indeed, he never promises to us salvation in Christ, without denouncing, on the other hand, vengeance on unbelievers; who by rejecting Christ bring death on themselves. [2] It must be further noticed, that the Apostle speaks of God's word, which is brought to us by the ministry of men. For delirious and even dangerous are those notions, that though the internal word is efficacious, yet that which proceeds from the mouth of man is lifeless and destitute of all power. I indeed admit that the power does not proceed from the tongue of man, nor exists in mere sound, but that the whole power is to be ascribed altogether to the Holy Spirit; there is, however, nothing in this to hinder the Spirit from putting forth his power in the word preached. For God, as he speaks not by himself, but by men, dwells carefully on this point, so that his truth may not be objected to in contempt, because men are its ministers. So Paul, by saying, that the Gospel is the power of God, (Romans 1:16.) designedly adorned with this distinction his own preaching, though he saw that it was slandered by some and despised by others. And when in another place, (Romans 10:8,) he teaches us that salvation is conferred by the doctrine of faith, he expressly says that it was the doctrine which was preached. We indeed find that God ever commends the truth administered to us by men, in order to induce us to receive it with reverence. Now, by calling the word quick or living he must be understood as referring to men; which appears still clearer by the second word, powerful, for he shows what sort of life it possesses, when he expressly says that it is efficacious; for the Apostle's object was to teach us what the word is to us. [3] The sword is a metaphorical word often used in Scripture; but the Apostle not content with a simple comparison, says, that God's word is sharper than any sword, even than a sword that cuts on both sides, or twoedged; for at that time swords were in common use, which were blunt on one side, and sharp on the other. Piercing even to the dividing asunder of the soul and spirit, or to the dividing of the soul and spirit, etc. The word soul means often the same with spirit; but when they occur together, the first includes all the affections, and the second means what they call the intellectual faculty. So Paul, writing to the Thessalonians, uses the words, when he prays God to keep their spirit, and soul, and body blameless until the coming of Christ, (1-Thessalonians 5:23,) he meant no other thing, but that they might continue pure and chaste in mind, and will, and outward actions. Also Isaiah means the same when he says, "My soul desired thee in the night; I sought thee with my spirit." (Isaiah 26:9.) What he doubtless intends to show is, that he was so intent on seeking God, that he applied his whole mind and his whole heart. I know that some give a different explanation; but all the soundminded, as I expect, will assent to this view. Now, to come to the passage before us, it is said that God's word pierces, or reaches to the dividing of soul and spirit, that is, it examines the whole soul of man; for it searches his thoughts and scrutinizes his will with all its desires. And then he adds the joints and marrow, intimating that there is nothing so hard or strong in man, nothing so hidden, that the powerful word cannot pervade it. [4] Paul declares the same when he says, that prophecy avails to reprove and to judge men, so that the secrets of the heart may come, to light. (1-Corinthians 14:24.) And as it is Christ's office to uncover and bring to light the thoughts from the recesses of the heart, this he does for the most part by the Gospel. Hence God's word is a discerner, (kritikos, one that has power to discern,) for it brings the light of knowledge to the mind of man as it were from a labyrinth, where it was held before entangled. There is indeed no thicker darkness than that of unbelief, and hypocrisy is a horrible blindness; but God's word scatters this darkness and chases away this hypocrisy. Hence the separating or discerning which the Apostle mentions; for the vices, hid under the false appearance of virtues, begin then to be known, the varnish being wiped away. And if the reprobate remain for a time in their hidden recesses, yet they find at length that God's word has penetrated there also, so that they cannot escape God's judgment. Hence their clamour and also their fury, for were they not smitten by the word, they would not thus betray their madness, but they would seek to elude the word, or by evasion to escape from its power, or to pass it by unnoticed; but these things God does not allow them to do. Whenever then they slander God's word, or become enraged against it, they show that they feel within its power, however unwillingly and reluctantly. [5]

Footnotes

1 - It has been a matter of dispute whether the "word" here is Christ, or the Scripture. The fathers as well as later divines are divided. The former is the opinion of Augustin, Ambrose, and also of Dr. Owen and Doddridge: and the latter is held by Chrysostom, Theophylact, and also by Calvin, Beza, Macknight, Scott, Stuart and Bloomfield. The latter is clearly the most suitable to the words of the passage. The only difficulty is in verse 13; but there a transition is evidently made from the word of God to God himself; and thus both are in remarkable manner connected together. -- Ed.

2 - See [19]Appendix P.

3 - See [20]Appendix Q.

4 - The metaphor of a sword is evidently carried on; the word is like the sword which "penetrates so as to separate the soul (the animal life) and the spirit, (the immortal part,) the joints also and the marrows, being even a strict judge of the thoughts and purposes of the heart." -- Ed.

For the word of God - The design of this and the following verse is obvious. It is to show that we cannot escape the notice of God; that all insincerity, unbelief, hypocrisy, will be detected by him; and that since our hearts are perfectly open before him, we should be sincere and should not attempt to deceive him. The sense is, that the truth of God is all-penetrating and searching, and that the real thoughts and intents of the heart will be brought to light, and that if there is insincerity and self-deception there can be no hope of escape. There has been a great variety of opinion here about the meaning of the phrase "the Word of God." Some have supposed that it means the Lord Jesus; others, the whole of the divine revelation; others the gospel; others the particular threatening referred to here. The "Word of God" is "what God speaks" - whether it be a promise or a threatening; whether it be Law or gospel; whether it be a simple declaration or a statement of a doctrine. The idea here is, that what "God had said" is suited to detect hypocrisy and to lay open the true nature of the feelings of the soul, so that there can be no escape for the guilty. His "truth" is adapted to bring out the real feelings, and to show man exactly what he is. Truth always has this power - whether preached, or read, or communicated by conversation, or impressed upon the memory and conscience by the Holy Spirit. There can be no escape from the penetrating, searching application of the Word of God. That truth has power to show what man is, and is like a penetrating sword that lays open the whole man; compare Isaiah 49:2. The phrase "the Word of God" here may be applied, therefore, to the "truth" of God, however made known to the mind. In some way it will bring out the real feelings, and show what man is.
Is quick - Greek ζῶν zōn - "living." It is not dead, inert, and powerless. It has a "living" power, and is energetic and active. It is "adapted" to produce this effect.
And powerful - Mighty. Its power is seen in awakening the conscience; alarming the fears; laying bare the secret feelings of the heart, and causing the sinner to tremble with the apprehension of the coming judgment. All the great changes in the moral world for the better, have been caused by the power of truth. They are such as the truth in its own nature is suited to effect, and if we may judge of its power by the greatness of the revolutions produced, no words can over-estimate the might of the truth which God has revealed.
Sharper than any two-edged sword - Literally, "two-mouthed" sword - δίστομον distomon. The word "mouth" was given to the sword because it seemed to "devour" all before it. It consumed or destroyed as a wild beast does. The comparison of the Word of God to a sword or to an arrow, is designed to show its power of penetrating the heart; Ecclesiastes 12:11, "The words of the wise are as goads, and as nails fastened by the masters of assemblies;" compare Isaiah 49:2. "And he hath made my mouth like a sharp sword;" Revelation 1:16, "And out of his mouth went a sharp two-edged sword;" Revelation 2:12, Revelation 2:16; Revelation 19:15. The comparison is common in the classics, and in Arabic poetry; see Gesenius, on Isaiah 49:2. The idea is that of piercing, or penetrating; and the meaning here is, that the Word of God reaches the "heart" - the very center of action, and lays open the motives and feelings of the man. It was common among the ancients to have a sword with two edges. The Roman sword was commonly made in this manner. The fact that it had two edges made it more easy to penetrate, as well as to cut with every way.
Piercing even to the dividing asunder - Penetrating so as to divide.
Soul and spirit - The animal life from the immortal soul. The former word here - ψυχή psuchē - "soul" - is evidently used to denote the "animal life," as distinguished from the mind or soul. The latter word - πνεῦμα pneuma - "spirit" - means the soul; the immaterial and immortal part; what lives when the animal life is extinct. This distinction occurs in 1-Thessalonians 5:23, "your whole spirit, and soul, and body;" and it is a distinction which we are constantly in the habit of making. There is the body in man - the animal life - and the immortal part that leaves the body when life is extinct. Mysteriously united, they constitute one man. When the animal life is separated from the soul, or when the soul leaves the animated body, the body dies, and life is extinct. To separate the one from the other is, therefore, the same as to take life - and this is the idea here, that the Word of God is like a sharp sword that inflicts deadly wounds. The sinner "dies;" that is, he becomes dead to his former hopes, or is "slain" by the Law; Romans 7:9, "I was alive without the law once, but when the commandment came, sin revived, and I died." This is the power referred to here - the power of destroying the hopes of the sinner; cutting him down under conviction; and prostrating him as if a sword had pierced his heart.
And of the joints and marrow - The figure is still continued of the sword that takes life. Such a sword would seem to penetrate even the joints and marrow of the body. It would separate the joints, and pierce through the very bones to the marrow. A similar effect, Paul says, is produced by truth. It seems to penetrate the very essence of the soul, and lay it all open to the view.
And is a discerner of the thoughts - It shows what the thoughts and intentions are. Prof. Stuart, Bloomfield, and some others, suppose that the reference here is to "God" speaking by his word. But the more natural construction certainly is, to refer it to the Word or truth of God. It is true that God searches the heart, and knows the thoughts, but that is not the truth which is prominent here. It is, that the thoughts and intents of the heart are brought out to view by the Word of God. And can anyone doubt this? see Romans 7:7. Is it not true that people are made to see their real character under the exhibition of the truth of God? That in the light of the Law they see their past lives to be sinful? That the exhibition of truth calls to their recollection many long-forgotten sins? And that their real feelings are brought out when the truth of God is proclaimed? Men then are made to look upon their motives as they had never done before, and to see in their hearts feelings whose existence they would not have suspected if it had not been for the exhibition of the truth. The exhibition of the truth is like pouring down the beams of the sun at midnight on a dark world; and the truth lays open the real feelings of the sinner as that sun would disclose the clouds of wickedness that are now performed under cover of the night. Many a man has a deep and fixed hostility to God and to his gospel who might never be sensible of it if the truth was not faithfully proclaimed. The particular idea here is, that the truth of God will detect the feelings of the hypocrite and self-deceiver. They cannot always conceal their emotions, and the time will come when truth, like light poured into the soul, will reveal their unbelief and their secret sins. They who are cherishing a hope of salvation, therefore, should be on their guard lest they mistake the name for the reality. Let us learn from this verse:
(1) The power of truth. It is "suited" to lay open the secret feelings of the soul. There is not an effect produced in awakening a sinner; or in his conviction, conversion, and sanctification, which the truth is not "adapted" to produce. The truth of God is not dead; nor suited to make people "worse;" nor designed merely to show its own "weakness," and to be a mere occasion on which the Holy Spirit acts on the mind; it is in its own nature Fitted to produce just the effects which are produced when it awakens, convicts, converts, and sanctifies the soul.
(2) the truth should be preached with the feeling that it is adapted to this end. Men who preach should endeavor to understand the nature of the mind and of the moral feelings, as really as he who would inflict a deadly wound should endeavor to understand enough about anatomy to know where the heart is, or he who administers medicine should endeavor to know what is adapted to remove certain diseases. And he who has no belief in the efficacy of truth to produce any effect, resembles one who should suppose that all knowledge of the human system was needless to him who wished to perform a surgical operation, and who should cut at random - piously leaving it with God to direct the knife; or he who should go into a hospital of patients and administer medicines indiscriminately - devoutly saying that all healing must come from God, and that the use of medicine was only to show its own weakness! Thus, many men seem to preach. Yet for aught that appears, truth is just as wisely adapted to save the soul as medicine is to heal the sick; and why then should not a preacher be as careful to study the nature of truth and its adaptedness to a particular end, as a student of the healing art is to understand the adaptedness of medicine to cure disease? The true way of preaching is, to feel that truth is adapted to the end in view; to select what is best suited for that end; to preach as if the whole result depended on getting that truth before the mind and into the heart - and then to leave the whole result with God - as a physician with right feelings will exert all his skill to save his patient, and then commit the whole question of life and health to God. He will be more likely to praise God intelligently who believes that he has wisely adapted a plan to the end in view, than he who believes that God works only at random.

For the word of God is quick, and powerful - Commentators are greatly divided concerning the meaning of the phrase Ὁ λογος τον Θεου, the word of God; some supposing the whole of Divine revelation to be intended; others, the doctrine of the Gospel faithfully preached; others, the mind of God or the Divine intellect; and others, the Lord Jesus Christ, who is thus denominated in John 1:1, etc., and Revelation 19:13; the only places in which he is thus incontestably characterized in the New Testament. The disputed text, 1-John 5:7, I leave at present out of the question. In the introduction to this epistle I have produced sufficient evidence to make it very probable that St. Paul was the author of this epistle. In this sentiment the most eminent scholars and critics are now agreed. That Jesus Christ, the eternal, uncreated Word, is not meant here, is more than probable from this consideration, that St. Paul, in no part of his thirteen acknowledged epistles, ever thus denominates our blessed Lord; nor is he thus denominated by any other of the New Testament writers except St. John. Dr. Owen has endeavored to prove the contrary, but I believe to no man's conviction who was able to examine and judge of the subject. He has not been able to find more than two texts which even appeared to look his way. The first is, Luke 1:2 : Us, which - were eye witnesses, and ministers του λογου, of the word; where it is evident the whole of our Lord's ministry is intended. The second is, Acts 20:32 : I commend you to God, and to the word of his grace; where nothing but the gracious doctrine of salvation by faith, the influence of the Divine Spirit, etc., etc., can be meant: nor is there any legitimate mode of construction with which I am acquainted, by which the words in either place can be personally applied to our Lord. That the phrase was applied to denominate the second subsistence in the glorious Trinity, by Philo and the rabbinical writers, I have already proved in my notes on John 1, where such observations are alone applicable.
Calmet, who had read all that either the ancients or moderns have said on this subject, and who does not think that Jesus Christ is here intended, speaks thus: "None of the properties mentioned here can be denied to the Son of God, the eternal Word; he sees all things, knows all things, penetrates all things, and can do all things. He is the ruler of the heart, and can turn it where he pleases. He enlightens the soul, and calls it gently and efficaciously, when and how he wills. Finally, he punishes in the most exemplary manner the insults offered to his Father and himself by infidels, unbelievers, and the wicked in general. But it does not appear that the Divine Logos is here intended,
1. Because St. Paul does not use that term to express the Son of God.
2. Because the conjunction γαρ, for, shows that this verse is an inference drawn from the preceding, where the subject in question is concerning the eternal rest, and the means by which it is to be obtained.
It is therefore more natural to explain the term of the word, order, and will of God, for the Hebrews represent the revelation of God as an active being, living, all-powerful, illumined, executing vengeance, discerning and penetrating all things. Thus The Wisdom of Solomon 16:26: 'Thy children, O Lord, know that it is not the growing of fruits that nourisheth man, but that it is thy word that preserveth them that put their trust in thee.' See Deuteronomy 8:3. That is, the sacred Scriptures point out and appoint all the means of life. Again, speaking of the Hebrews who were bitten with the fiery serpents, the same writer says, 16:12: 'For it was neither herb nor mollifying plaster that restored them to health, but thy word, O Lord, which healeth all things;' i.e. which describes and prescribes the means of healing. And it is very likely that the purpose of God, sending the destroying angel to slay the firstborn in Egypt is intended by the same expression, The Wisdom of Solomon 18:15, 16: 'Thine almighty word leaped down from heaven out of thy royal throne, as a fierce man of war into a land of destruction, and brought thine unfeigned commandment as a sharp sword, and, standing up, filled all things with death.' This however may be applied to the eternal Logos, or uncreated Word.
"And this mode of speech is exactly conformable to that of the Prophet Isaiah, Isaiah 55:10, Isaiah 55:11, where to the word of God, spoken by his prophets, the same kind of powers are attributed as those mentioned here by the apostle: For as the rain cometh down and the snow from heaven, and returneth not thither, but watereth the earth, and maketh it bring forth and bud, that it may give seed to the sower, and bread to the eater; so shall my Word Be that Goeth Forth Out of My Mouth: it shall not return unto me void; but it shall accomplish that which I please, and it shall prosper in the thing whereto I sent it. The centurion seems to speak a similar language, Luke 7:7 : But say in a word, (αλλα ειπε λογῳ, speak to thy word), and my servant shall be healed." This is the sum of what this very able commentator says on the subject.
In Dr. Dodd's collections we find the following: -
"The word of God, which promises to the faithful, an entrance into God's rest in David's time, and now to us, is not a thing which died or was forgotten as soon as it was uttered, but it continues one and the same to all generations; it is ζων, quick or living. So Isaiah says: The word of our God shall stand for ever; Isaiah 40:8. Compare Isaiah 51:6; Isaiah 55:11; 1 Esdras 4:38; John 3:34; 1-Peter 1:23. And powerful, ενεργης, efficacious, active; sufficient, if it be not actually hindered, to produce its effects; effectual, Plm 1:6. See 2-Corinthians 10:4; 1-Thessalonians 2:13. And sharper than any two-edged sword; τομωτερος ὑπερ, more cutting than. The word of God penetrates deeper into a man than any sword; it enters into the soul and spirit, into all our sensations, passions, appetites, nay, to our very thoughts; and sits as judge of the most secret intentions, contrivances, and sentiments of the heart. Phocylides has an expression very similar to our author, where he says, of reason, 'that it is a weapon which penetrates deeper into a man than a sword.' See also Isaiah 40:4; Ephesians 6:17; Revelation 1:16; Revelation 2:16.
"Piercing even to the dividing asunder of soul and spirit. - When the soul is thus distinguished from the spirit, by the former is meant that inferior faculty by which we think of and desire what concerns our present being and welfare. By spirit is meant a superior power by which we prefer future things to present, by which we are directed to pursue truth and right above all things, and even to despise what is agreeable to our present state, if it stand in competition with, or is prejudicial to, our future happiness. See 1-Thessalonians 5:23. Some have thought that by the expression before us is implied that the word of God is able to bring death, as in the case of Ananias and Sapphira; for, say they, if the soul and spirit, or the joints and marrow are separated one from another, it is impossible that life can remain. But perhaps the meaning of the latter clause may rather be: 'It can divide the joints and divide the marrow; i.e. enter irresistibly into the soul, and produce some sentiment which perhaps it would not willingly have received; and sometimes discover and punish secret, as well as open wickedness.' Mr. Pierce observes that our author has been evidently arguing from a tremendous judgment of God upon the ancient Israelites, the ancestors of those to whom this epistle is directed; and in this verse, to press upon them that care and diligence he had been recommending, he sets before them the efficacy and virtue of the word of God, connecting this verse with the former by a for in the beginning of it; and therefore it is natural to suppose that what he says of the word of God may have a relation to somewhat remarkable in that sore punishment of which he had been speaking, particularly to the destruction of the people by lightning, or fire from heaven. See Leviticus 10:1-5; Numbers 11:1-3, Numbers 16:35; Psalm 78:21. All the expressions in this view will receive an additional force, for nothing is more quick and living, more powerful and irresistible, sharp and piercing, than lightning. If this idea be admitted, the meaning of the last clause in this verse will be, 'That the word of God is a judge, to censure and punish the evil thoughts and intents of the heart.' And this brings the matter home to the exhortation with which our author began, Hebrews 3:12, Hebrews 3:13; for under whatever disguise they might conceal themselves, yet, from such tremendous judgments as God executed upon their fathers, they might learn to judge as Moses did, Numbers 32:23 : If ye will not do so, ye have sinned against the Lord; and be sure your sin will find you out." See Hammond, Whitby, Sykes, and Pierce.
Mr. Wesley's note on this verse is expressed with his usual precision and accuracy: -
"For the word of God - preached, Hebrews 4:2, and armed with threatenings, Hebrews 4:3, is living and powerful - attended with the power of the living God, and conveying either life or death to the hearers; sharper than any two-edged sword - penetrating the heart more than this does the body; piercing quite through, and laying open, the soul and spirit, joints and marrow - the inmost recesses of the mind, which the apostle beautifully and strongly expresses by this heap of figurative words; and is a discerner, not only of the thoughts, but also of the intentions."
The law, and the word of God in general, is repeatedly compared to a two-edged sword among the Jewish writers, חרב שתי פיפיות chereb shetey piphiyoth, the sword with the two mouths. By this sword the man himself lives, and by it he destroys his enemies. This is implied in its two edges. See also Schoettgen.
Is a discerner of the thoughts - Και κριτικος ενθυμησεων και εννοιων καρδιας· Is a critic of the propensities and suggestions of the heart. How many have felt this property of God's word where it has been faithfully preached! How often has it happened that a man has seen the whole of his own character, and some of the most private transactions of his life, held up as it were to public view by the preacher; and yet the parties absolutely unknown to each other! Some, thus exhibited, have even supposed that their neighbors must have privately informed the preacher of their character and conduct; but it was the word of God, which, by the direction and energy of the Divine Spirit, thus searched them out, was a critical examiner of the propensities and suggestions of their hearts, and had pursued them through all their public haunts and private ways. Every genuine minister of the Gospel has witnessed such effects as these under his ministry in repeated instances.
But while this effect of the word or true doctrine of God is acknowledged, let it not be supposed that it, of itself can produce such effects. The word of God is compared to a hammer that breaks the rock in pieces, Jeremiah 23:29; but will a hammer break a stone unless it is applied by the skill and strength of some powerful agent? It is here compared to a two-edged sword; but will a sword cut or pierce to the dividing of joints and marrow, or separation of soul and spirit, unless some hand push and direct it? Surely, no. Nor can even the words and doctrine of God produce any effect but as directed by the experienced teacher, and applied by the Spirit of God. It is an instrument the most apt for the accomplishing of its work; but it will do nothing, can do nothing, but as used by the heavenly workman. To this is the reference in the next verse.

(4) For the (e) word of God [is] (f) quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of (g) soul and (h) spirit, and of the joints and marrow, and [is] a discerner of the thoughts and intents of the heart.
(4) An amplification taken from the nature of the word of God, so powerful that it enters even to the deepest and most inward and secret parts of the heart, fatally wounding the stubborn, and openly reviving the believers.
(e) The doctrine of God which is preached both in the law and in the gospel.
(f) He calls the word of God living, because of the effect it has on those to whom it is preached.
(g) He calls the seat of emotions "soul".
(h) By "spirit" he means the mind.

For the word of God is quick and powerful,.... This is to be understood of Christ, the essential Word of God; for the Word of God was a known name of the Messiah among the Jews; See Gill on John 1:1 and therefore the apostle makes use of it when writing to them: and the words are introduced as a reason why care should be taken, that men fall not off from the Gospel, because Christ, the author, sum, and substance of it, is the living God, omnipotent and omniscient; for not a thing, but a person is spoken of, who is a Judge, and a critical discerner of the secrets of men's hearts: and certain it is, that this Word is spoken of as a person, and is said to be a priest in the following verses; to which may be added, that the several things said of the Word exactly agree with Christ: he is "the Word of God"; as the word is the birth of the mind, he is the only begotten of the Father; he is the Word that spoke for the elect in the council and covenant of grace, and that spoke all things out of nothing in creation; he is the Word that has been promised, and spoken of by the prophets from the beginning of the world; and is the interpreter of his Father's mind, and our Advocate with the Father: he is
quick, or, as it may be better rendered, "living"; he has life in himself as God, he is the living God; he is the living Redeemer and Mediator, and he lives for ever as man; he is the author and giver of life, natural, spiritual, and eternal: and he is powerful, as he appears to be in the creation and sustaining of all things; in his miracles and ministrations; in the work of man's redemption; in the preservation of his people, and in his advocacy and intercession:
and sharper than any twoedged sword; or "more cutting than one", by the words of his mouth, by the power of his Spirit, and the efficacy of his grace; for his mouth itself is as a sharp sword, and out of it comes forth one, Isaiah 49:2 by which he pierces the hearts of men, cuts them to the quick, and lays them open. Jehovah is called a twoedged sword with the Jews (m); and Philo the Jew speaks of the flaming sword of the Logos (n).
Piercing even to the dividing asunder soul and spirit, and of the joints and marrow; the like property Philo the Jew ascribes to the "Logos", or Word; he calls him "a cutter", and says he cuts and divides all things, even all sensible things, yea, atoms, and things indivisible (o); the apostle seems here to have respect to the several names with which the soul of man is called by the Jews, , "soul, spirit, and breath" (p); the latter of these, they say, dwells between the other two. Some by the soul understand the natural and unregenerate part in man, and by the spirit the renewed and regenerate part, which though sometimes are not so easily distinguished by men, yet they are by Christ; others think the soul designs the inferior faculties, the affections; and the spirit the superior ones, the mind and understanding; but the apostle's meaning seems to be this, that whereas the soul and spirit are invisible, and the joints and marrow are covered and hid; so sharp and quick sighted, and so penetrating is the divine Word, that it reaches the most secret and hidden things of men: and this sense is confirmed by what follows,
and is a discerner of the thoughts and intents of the heart; Christ knows what is in man; he is the searcher of the hearts, and the trier of the reins of the children of men; and this will be more apparent at the last day, when he will make manifest the counsels of the heart, and will critically inquire, and accurately judge of them.

For--Such diligent striving (Hebrews 4:11) is incumbent on us FOR we have to do with a God whose "word" whereby we shall be judged, is heart-searching, and whose eyes are all-seeing (Hebrews 4:13). The qualities here attributed to the word of God, and the whole context, show that it is regarded in its JUDICIAL power, whereby it doomed the disobedient Israelites to exclusion from Canaan, and shall exclude unbelieving so-called Christians from the heavenly rest. The written Word of God is not the prominent thought here, though the passage is often quoted as if it were. Still the word of God (the same as that preached, Hebrews 4:2), used here in the broadest sense, but with special reference to its judicial power, INCLUDES the Word of God, the sword of the Spirit with double edge, one edge for convicting and converting some (Hebrews 4:2), and the other for condemning and destroying the unbelieving (Hebrews 4:14). Revelation 19:15 similarly represents the Word's judicial power as a sharp sword going out of Christ's mouth to smite the nations. The same word which is saving to the faithful (Hebrews 4:2) is destroying to the disobedient (2-Corinthians 2:15-16). The personal Word, to whom some refer the passage, is not here meant: for He is not the sword, but has the sword. Thus reference to Joshua appropriately follows in Hebrews 4:8.
quick--Greek, "living"; having living power, as "the rod of the mouth and the breath of the lips" of "the living God."
powerful--Greek, "energetic"; not only living, but energetically efficacious.
sharper--"more cutting."
two-edged--sharpened at both edge and back. Compare "sword of the Spirit . . . word of God" (Ephesians 6:17). Its double power seems to be implied by its being "two-edged." "It judges all that is in the heart, for there it passes through, at once punishing [unbelievers] and searching [both believers and unbelievers]" [CHRYSOSTOM]. PHILO similarly speaks of "God passing between the parts of Abraham's sacrifices (Genesis 15:17, where, however, it is a 'burning lamp' that passed between the pieces) with His word, which is the cutter of all things: which sword, being sharpened to the utmost keenness, never ceases to divide all sensible things, and even things not perceptible to sense or physically divisible, but perceptible and divisible by the word." Paul's early training, both in the Greek schools of Tarsus and the Hebrew schools at Jerusalem, accounts fully for his acquaintance with Philo's modes of thought, which were sure to be current among learned Jews everywhere, though Philo himself belonged to Alexandria, not Jerusalem. Addressing Jews, he by the Spirit sanctions what was true in their current literature, as he similarly did in addressing Gentiles (Acts 17:28).
piercing--Greek, "coming through."
even to the dividing asunder of soul and spirit--that is, reaching through even to the separation of the animal soul, the lower part of man's incorporeal nature, the seat of animal desires, which he has in common with the brutes; compare the same Greek, 1-Corinthians 2:14, "the natural [animal-souled] man" (Jde 1:19), from the spirit (the higher part of man, receptive of the Spirit of God, and allying him to heavenly beings).
and of the joints and marrow--rather, "(reaching even TO) both the joints (so as to divide them) and marrow." Christ "knows what is in man" (John 2:25): so His word reaches as far as to the most intimate and accurate knowledge of man's most hidden parts, feelings, and thoughts, dividing, that is, distinguishing what is spiritual from what is carnal and animal in him, the spirit from the soul: so Proverbs 20:27. As the knife of the Levitical priest reached to dividing parts, closely united as the joints of the limbs, and penetrated to the innermost parts, as the marrows (the Greek is plural); so the word of God divides the closely joined parts of man's immaterial being, soul and spirit, and penetrates to the innermost parts of the spirit. The clause (reaching even to) "both the joints and marrow" is subordinate to the clause, "even to the dividing asunder of soul and spirit." (In the oldest manuscripts as in English Version, there is no "both," as there is in the clause "both the joints and . . . which marks the latter to be subordinate). An image (appropriate in addressing Jews) from the literal dividing of joints, and penetrating to, so as to open out, the marrow, by the priest's knife, illustrating the previously mentioned spiritual "dividing of soul from spirit," whereby each (soul as well as spirit) is laid bare and "naked" before God; this view accords with Hebrews 4:13. Evidently "the dividing of the soul from the spirit" answers to the "joints" which the sword, when it reaches unto, divides asunder, as the "spirit" answers to the innermost "marrow." "Moses forms the soul, Christ the spirit. The soul draws with it the body; the spirit draws with it both soul and body." ALFORD'S interpretation is clumsy, by which he makes the soul itself, and the spirit itself, to be divided, instead of the soul from the spirit: so also he makes not only the joints to be divided asunder, but the marrow also to be divided (?). The Word's dividing and far penetrating power has both a punitive and a healing effect.
discerner of the thoughts--Greek, "capable of judging the purposes."
intents--rather, "conceptions" [CRELLIUS]; "ideas" [ALFORD]. AS the Greek for "thoughts" refers to the mind and feelings, so that for "intents," or rather "mental conceptions," refers to the intellect.

For the word of God. The Israelites came short because they refused to hear the word of the Lord. If we could enter in, we must take heed to the word. It is living and active (Revision), sharper than any two-edged sword. Cutting keenly and in all directions.
Dividing of soul and spirit. It not only gives life, but slays, as was the case with the Israelites who fell in the wilderness, and pierces to the soul and spirit. It reaches the very fountains of life.
A discerner of the thoughts. It lays bare the thoughts and the intentions.
Neither is there any creature. In Christ appears the Word in personal form, while in the gospel we have his spoken word. Here the reference is to the personal Word. Every creature is manifest before him, and all our deeds and thoughts are open to his eyes.

For the word of God - Preached, Hebrews 4:2, and armed with threatenings, Hebrews 4:3. Is living and powerful - Attended with the power of the living God, and conveying either life or death to the hearers. Sharper than any two - edged sword - Penetrating the heart more than this does the body. Piercing - Quite through, and laying open. The soul and spirit, joints and marrow - The inmost recesses of the mind, which the apostle beautifully and strongly expresses by this heap of figurative words. And is a discerner - Not only of the thoughts, but also of the intentions.
