Wherewith shall a young man cleanse his way? In this place he repeats, in different words, the same truth which he formerly advanced, That, however much men may pique themselves upon their own works, there is nothing pure in their life until they have made a complete surrender of themselves to the word of the Lord. The more effectually to excite them to this, he produces, in an especial manner, the example of children or youths. In mentioning these, he by no means gives an unbridled license to those who have arrived at mature years, or who are aged, as if they were competent to regulate their own life, and as if their own prudence served as a law to them; but because youth puts men where two ways meet, and renders it imperative for them to select the course of life which they mean to follow, he declares that, when a person sets about the regulation of his life, no advice will prove of any advantage, unless he adopts the law of God as his rule and guide. In this way the prophet stimulates men to an early and seasonable regulation of their manners, and not to delay doing so any longer, agreeably to the words of Solomon, "Remember thy Creator in thy youth, ere the days of trouble come, and the years which shall be grief unto thee," Ecclesiastes 12:1 They who defer from time to time become hardened in their vicious practices, and arrive at mature years, when it is too late to attempt a reformation. There is another reason, arising from the fact, of the carnal propensities being very powerful in youth, requiring a dortble restraint; and the more they are inclined to excess, the greater is the necessity for curbing their licentiousness. The prophet, therefore, not without reason, exhorts them particularly to attend to the observance of the law. We may reason from the greater to the less; for if the law of God possesses the power of restraining the impetuosity of youth, so as to preserve pure and upright all who take it for their guide, then, assuredly, when they come to maturity, and their irregular desires are considerably abated, it will prove the best antidote for correcting their vices. The reason, therefore, of so much evil prevailing in the world, arises from men wallowing in their own impurity, and being disposed to yield more to their own inclination than to heavenly instruction. The only sure protection is, to regulate ourselves according to God's word. Some, wise in their own conceit, throw themselves into the snares of Satan, others, from listlessness and languor, live a vile and wicked life.
Wherewithal - This begins the second portion of the psalm, extending to Psalm 119:16, in which all the verses begin with the second letter of the Hebrew alphabet (ב b), indicated in our translation by the word Beth. These names of the letters, inserted for convenience, are no part of the psalm, as it is not so marked in the original. This mode of indicating the divisions of the psalm is special to our version. It is not in the Septuagint, the Latin Vulgate, or the German versions. The word wherewithal means "by what" (Hebrew); that is, What means shall a young man adopt by which he may "cleanse his way?" it indicates a state of inquiry. The case supposed is that of a young man pondering the question how he may be saved from the corruptions of his own heart, and escape the temptations to which he is exposed in early years, and lead a pure and upright life. There can be no more important inquiry for one just entering on the journey of life; there can be found nowhere a more just and comprehensive answer than is contained in this single verse. All the precepts of ancient and modern wisdom, all the teachings of pagan morality and religion, and all the results of the experience of mankind, could furnish nothing in addition to what is here suggested. The world has no higher wisdom than this by which to guide a young man, so that he may lead a holy life.
Shall a young man - The remark here might be applied also to those who are in middle life, or even to those who are in more advanced years, but it is applied here especially to the young, because it may be supposed that in the other cases the matter may be regarded as settled by experience; because to the young, as they commence life, the inquiry is so momentous; and because it is a question which it may be supposed will come up before the mind of every young man who has any right aspirations, and any proper conception of the dangers which encompass his path.
Cleanse his way? - Make his course of life pure and upright. The language does not necessarily imply that there had been any previous impurity or vice, but it has particular reference to the future: not how he might cleanse himself from past offences, but how he might make the future pure. The inquiry is, how he might conduct himself - what principles he could adopt - under what influence he could bring himself - so that his future course would be honest, honorable, upright.
By taking heed thereto - The word "thereto" is not in the original. The Hebrew is, "To keep according to thy word;" or, "in keeping according to thy word." Prof. Alexander supposes that this means "to keep it (his way) according to thy word;" and that the whole is a question - "How may a young man so cleanse his way as to keep it according to thy word?" - and that the answer to the question is to be found in the general strain of the psalm, or in the general principles laid down in the psalm. But it is clear that the answer to the question must be found in the verse, or not found at all; and the most natural construction is that in our translation. So DeWette renders it: "How can a young man walk guiltless? If (or, when) he holds (or, keeps) himself according to thy word." The meaning clearly is If he governs himself according to the law of God - if he makes that law the rule of his life and conduct, he would be enabled to do it. All other things might fail; this rule would never fail, in making and keeping a man pure. The more principles of common honesty, the principles of honor, the considerations of self-interest, the desire of reputation - valuable as they may be - would not constitute a security in regard to his conduct; the law of God would, for that is wholly pure.
A young man cleanse his way - ארח orach, which we translate way here, signifies a track, a rut, such as is made by the wheel of a cart or chariot. A young sinner has no broad beaten path; he has his private ways of offense, his secret pollutions: and how shall he be cleansed from these? how can he be saved from what will destroy mind, body, and soul? Let him hear what follows; the description is from God.
1. He is to consider that his way is impure; and how abominable this must make him appear in the sight of God.
2. He must examine it according to God's word, and carefully hear what God has said concerning him and it.
3. He must take heed to it, לשמר lishmor, to keep guard, and preserve his way - his general course of life, from all defilement.
BETH. Wherewithal shall a (a) young man cleanse his way? by taking heed [thereto] according to thy word.
(a) Because youth is most given to licentiousness, he chiefly warns them to frame their lives after God's word.
BETH.--The Second Part.
BETH. Wherewith shall a young man cleanse his way?.... Some think David means himself, and that he was a young man when he wrote this psalm; and which they think is confirmed by Psalm 119:100; but neither of them seem conclusive; rather any young man is meant, and who is particularly mentioned, because young men are liable to sins and snares, to carnal lusts and sensual pleasures, which are of a defiling nature. Some are of opinion that a young man, or babe in Christ, is intended, that needs direction in his way, and instruction about the manner of cleansing it. But the former sense seems best, and expresses the concern of the psalmist for the education and right information of youth; which is a matter of great moment and advantage to families, neighbourhoods, and commonwealths. The question supposes the young man to be impure, as every man is by birth, being conceived in sin, and shapen in iniquity; is a transgressor from the womb, and his heart, ways, and actions, evil from his youth: and the difficulty is, how he shall be cleansed; how one so impure in his nature, heart, and ways, can be just with God, or become undefiled in the way, as in Psalm 119:1; to which some reference may be had: or how he can have his heart made pure, or a clean one be created in him; or how his way, life, and conversation, may be corrected, reformed, and amended. The answer is,
by taking heed thereto according to thy word; that is, to his way and course of life, and steering it according to the direction of the word of God. But I think the words may be better rendered and supplied thus, "by observing what is according to thy word" (p); which shows how a sinner is to be cleansed from his sins by the blood of Christ, and justified by his righteousness, and be clean through his word; and also how and by whom the work of sanctification is wrought in the heart, even by the Spirit of God, by means of the word; and what is the rule of a man's walk and conversation: he will find the word of God to be profitable, to inform in the doctrines of justification and pardon, to acquaint him with the nature of regeneration and sanctification; and for the correction and amendment of his life and manners, and for his instruction in every branch of righteousness, 2-Timothy 3:16.
(p) "observando secundum verbum tuum", Cocceius.
To original corruption all have added actual sin. The ruin of the young is either living by no rule at all, or choosing false rules: let them walk by Scripture rules. To doubt of our own wisdom and strength, and to depend upon God, proves the purpose of holiness is sincere. God's word is treasure worth laying up, and there is no laying it up safe but in our hearts, that we may oppose God's precepts to the dominion of sin, his promises to its allurements, and his threatenings to its violence. Let this be our plea with Him to teach us his statutes, that, being partakers of his holiness, we may also partake of his blessedness. And those whose hearts are fed with the bread of life, should with their lips feed many. In the way of God's commandments there is the unsearchable riches of Christ. But we do not meditate on God's precepts to good purpose, unless our good thoughts produce good works. I will not only think of thy statutes, but do them with delight. And it will be well to try the sincerity of our obedience by tracing the spring of it; the reality of our love by cheerfulness in appointed duties.
BETH. (Psalm 119:9-16).
The whole verse may be read as a question; for,
by taking heed--is better, "for" taking heed, that is, so as to do it. The answer is implied, and inferable from Psalm 119:5, Psalm 119:10, Psalm 119:18, &c., that is, by God's grace.
The eightfold Beth. Acting in accordance with the word of God, a young man walks blamelessly; the poet desires this, and supplicates God's gracious assistance in order to it. To purify or cleanse one's way or walk (זכּה, cf. Psalm 73:13; Proverbs 20:9) signifies to maintain it pure (זך, root זך, Arab. zk, to prick, to strike the eye, nitere;
(Note: The word receives the meaning of νικᾶν (vid., supra, p. 367), like Arab. ḏhr and bhr, from the signification of outshining = overpowering.)
vid., Fleischer in Levy's Chaldisches Wrterbuch, i. 424) from the spotting of sin, or to free it from it. Psalm 119:9 is the answer to the question in Psalm 119:9; לשׁמר signifies custodiendo semetipsum, for שׁמר can also signify "to be on one's guard" without נפשׁו (Joshua 6:18). The old classic (e.g., Psalm 18:31) אמרתך alternates throughout with דּברך; both are intended collectively. One is said to hide (צפן) the word in one's heart when one has it continually present with him, not merely as an outward precept, but as an inward motive power in opposition to selfish action (Job 23:12). In Psalm 119:12 the poet makes his way through adoration to petition. ספּרתּי in Psalm 119:13 does not mean enumeration, but recounting, as in Deuteronomy 6:7. עדות is the plural to עדוּת; עדות, on the contrary, in Psalm 119:138 is the plural to עדה: both are used of God's attestation of Himself and of His will in the word of revelation. כּעל signifies, according to Psalm 119:162, "as over" (short for כּאשׁר על), not: as it were more than (Olshausen); the כּ would only be troublesome in connection with this interpretation. With reference to הון, which has occurred already in Psalm 44:13; Psalm 112:3 (from הון, Arab. hawn, to be light, levem), aisance, ease, opulence, and concrete, goods, property, vid., Fleischer in Levy's Chald. Wrterb. i. 423f. ארחתיך, Psalm 119:15, are the paths traced out in the word of God; these he will studiously keep in his eye.
A young man - Or, any man. But he names the young man, because such are commonly void of wisdom and experience, and exposed to many and great temptations. Cleanse - Purge himself from all filthiness of flesh and spirit.
