We will shout for joy in thy victory, And in the name of our God we will set up our standards; The LORD fulfil all thy petitions.

Now I know. Here there follows grateful rejoicing, in which the faithful declare that they have experienced the goodness of God in the preservation of the king. To this there is at the same time added a doctrine of faith, namely, that God showed by the effect that he put forth his power in maintaining the kingdom of David, because it was founded upon his calling. The meaning is, It appears from certain experience, that God is the guardian of the kingdom which he himself set up, and of which he is the founder. For David is called Messiah, or anointed, that the faithful might be persuaded that he was a lawful and sacred king, whom God had testified, by outward anointing, to be chosen by himself. Thus, then, the faithful ascribe to the grace of God the deliverance which had been wrought for David from the greatest dangers, and at the same time, particularly mention the cause of this to be, that God had determined to protect and defend him who, by his commandment, had been anointed king over his people. They confirm still more clearly their hope, with respect to the future, in the following clause: God will hear him out of heaven I do not translate the verb which is here used into the past tense, but retain the future: for I have no doubt, that from the experience which God had already given them of his goodness, they concluded that it would be hereafter exercised in the continual preservation of the kingdom. Here the Psalmist makes mention of another sanctuary, [1] namely, a heavenly. As God then graciously vouchsafed to descend among the Israelites, by the ark of the covenant, in order to make himself more familiarly known to them; so, on the other hand, he intended to draw the minds of his people upwards to himself, and thereby to prevent them from forming carnal and earthly conceptions of his character, and to teach them that he was greater than the whole world. Thus, under the visible sanctuary, which was made with hands, there is set forth the fatherly goodness of God, and his familiarity with his people; while, under the heavenly sanctuary, there is shown his infinite power, dominion, and majesty. The words, In the mightiness of the salvation, mean his mighty salvation, or his saving power. Thus, in the very expression there is a transposing of the words. The sense comes to this: May God by his wonderful power, preserve the king who was anointed by his commandment! The Holy Spirit, who dictated this prayer, saw well that Satan would not suffer David to live in peace, but would put forth all his efforts to oppose him, which would render it necessary for him to be sustained by more than human power. I do not, however, disapprove of the other exposition which I have marked on the margin, according to which the faithful, for their greater encouragement, set before themselves this truth, that the salvation of God's right hand is in mightiness; in other words, is sufficiently strong to overcome all impediments.

Footnotes

1 - Different from "the sanctuary" mentioned in verse second.

Now know I that the Lord saveth his anointed - Saveth, or will save, the king, who had been anointed, or consecrated by anointing to that office. Compare the note at Psalm 2:2. This, according to the view given in the introduction, is the response of the king. It expresses his confident assurance of success from the interest which the people had expressed in the enterprise, as referred to in the previous verses, and from the earnestness of their prayers in his behalf and in behalf of the enterprise. They had manifested such zeal in the cause, and they had offered so earnest petitions, that he could not doubt that God would smile favorably on the undertaking, and would grant success.
He will hear him from his holy heaven - Margin, "from the heaven of his holiness." So the Hebrew. Compare 1-Chronicles 21:26; 2-Chronicles 7:14; Nehemiah 9:27-28; Psalm 14:2; Psalm 102:19. heaven is represented as the dwelling-place of God, and it is there that he hears and answers our prayers. The meaning of the word "hear" in this passage is, that he will "favorably hear," or regard; that is, that he will "answer" the petition, or grant the request.
With the saving strength - That is, he will interpose with that saving strength. Literally, "with the strengths of salvation." The answer to the prayer will be manifest in the strength or power put forth by him to save.
Of his right hand - The right hand is the instrument by which mainly we execute our purposes; and by constant use it becomes in fact more fully developed, and is stronger than the left band. Hence, it is used to denote "strength." See Exodus 15:6; Judges 5:26; see Psalm 17:7, note; Psalm 18:35, note.

Now know I that the Lord saveth his anointed - These are probably the words of the priest after the victim had been consumed; and those signs had accompanied the offering, which were proofs of God's acceptance of the sacrifice; and, consequently, that the campaign would have a successful issue. David is God's anointed; therefore, he is under his especial care. He will hear him. David must continue to pray, and to depend on God; else he cannot expect continual salvation. David has vast multitudes of enemies against him; he, therefore, requires supernatural help. Because of this, God will hear him with the saving strength of his right hand.
The Hand of God is his power, the Right hand, his almighty power; the Strength of his right hand, his almighty power in action; the Saving strength of his right hand, the miraculous effects wrought by his almighty power brought into action. This is what David was to expect; and it was the prospect of this that caused him and his officers to exult as they do in the following verse.

Now (e) know I that the LORD saveth his anointed; he will hear him from his (f) holy heaven with the saving strength of his right hand.
(e) The Church feels that God had heard their petition.
(f) As by the visible sanctuary God's familiarity appeared toward his people, so by the heavenly is meant his power and majesty.

Now know I that the Lord saveth his Anointed,.... Not David, though he was the anointed of the God of Jacob, and was anointed with material oil to be king of Israel by Samuel, at the express order of God himself; but David is not here speaking of himself, nor the church of him, but of the Messiah; anointed by Jehovah king over his holy hill of Zion, with the oil of gladness, or the Holy Spirit. The church in prayer rises in her faith, and is strongly assured of the salvation of the Messiah; that though his troubles would be many and great, he should be delivered out of them all; should be heard and helped in the day of salvation, and be freed from the sorrows of death and hell, he should be encompassed with; that he should be raised from the dead; have all power in heaven and earth given him; ascend on high, and triumph over all his enemies; and all his people, all the members of his body, should be saved through him, which is in a sense the salvation of himself;
he will hear him from his holy heaven; where his throne and temple are, which is the habitation of his holiness, whither the prayers of the Messiah when on earth ascended, where they were received, heard, and answered. Before the church prays that he might be heard, now she believes he would; and that,
with the saving strength of his right hand; that is, by the exertion of his mighty power, in strengthening him as man to bear up under his sorrows, go through his work, and finish it; by upholding him with his right hand while engaged in it, and by raising him up from the dead with it, and setting him down at it in the highest heavens.

He speaks as if suddenly assured of a hearing.
his anointed--not only David personally, but as the specially appointed head of His Church.
his holy heaven--or, literally, "the heavens of His holiness," where He resides (Psalm 2:6; Psalm 11:4).
saving . . . hand--His power which brings salvation.

(Hebrews.: 20:7-9) While Psalm 20:2 were being sung the offering of the sacrifice was probably going on. Now, after a lengthened pause, there ascends a voice, probably the voice of one of the Levites, expressing the cheering assurance of the gracious acceptance of the offering that has been presented by the priest. With עתּה or ועתּה, the usual word to indicate the turning-point, the instantaneous entrance of the result of some previous process of prolonged duration, whether hidden or manifest (e.g., 1-Kings 17:24; Isaiah 29:22), is introduced. howshiya` is the perfect of faith, which, in the certainty of being answered, realises the fulfilment in anticipation. The exuberance of the language in Psalm 20:7 corresponds to the exuberance of feeling which thus finds expression.
In Psalm 20:3 the answer is expected out of Zion, in the present instance it is looked for from God's holy heavens; for the God who sits enthroned in Zion is enthroned for ever in the heavens. His throne on earth is as it were the vestibule of His heavenly throne; His presence in the sanctuary of Israel is no limitation of His omnipresence; His help out of Zion is the help of the Celestial One and Him who is exalted above the heaven of heavens. גּבוּרות does not here mean the fulness of might (cf. Psalm 90:10), but the displays of power (Psalm 106:2; Psalm 145:4; Psalm 150:2; Psalm 63:1-11 :15), by which His right hand procures salvation, i.e., victory, for the combatant. The glory of Israel is totally different from that of the heathen, which manifests itself in boastful talk. In Psalm 20:8 הזכּירוּ or יזכּירוּ must be supplied from the נזכּיר in Psalm 20:8 (lxx μεγαλυνθησόμεθα = נגביר, Psalm 12:5); הזכּיר בּ, to make laudatory mention of any matter, to extol, and indirectly therefore to take credit to one's self for it, to boast of it (cf. הלּל בּ, Psalm 44:9). According to the Law Israel was forbidden to have any standing army; and the law touching the king (Deuteronomy 17:16) speaks strongly against his keeping many horses. It was also the same under the judges, and at this time under David; but under Solomon, who acquired for himself horses and chariots in great number (1-Kings 10:26-29), it was very different. It is therefore a confession that must belong to the time of David which is here made in Psalm 20:8, viz., that Israel's glory in opposition to their enemies, especially the Syrians, is the sure defence and protection of the Name of their God alone. The language of David to Goliath is very similar, 1-Samuel 17:45. The preterites in Psalm 20:9 are praet. confidentiae. It is, as Luther says, "a song of triumph before the victory, a shout of joy before succour." Since קוּם does not mean to stand, but to rise, קמנוּ assumes the present superiority of the enemy. But the position of affairs changes: those who stand fall, and those who are lying down rise up; the former remain lying, the latter keep the field. The Hithpa. התעודד signifies to show one's self firm, strong, courageous; like עודד, Psalm 146:9; Psalm 147:6, to strengthen, confirm, recover, from עוּד to be compact, firm, cogn. Arab. âd f. i., inf. aid, strength; as, e.g., the Koran (Sur. xxxviii. 16) calls David dhâ-l-aidi, possessor of strength, II ajjada, to strengthen, support, and Arab. 'dd, inf. add, strength superiority, V tāddada, to show one's self strong, brave, courageous.

Now - We are already sure of victory by the consideration of God's power and faithfulness and love to David, and to his people. They speak as one person, because they were unanimous in this prayer. Saveth - Will certainly save. Strength - This shews how God will hear him, even by saving him with a strong hand.
