Burnt sacrifice - The olah here mentioned was a bloody sacrifice. The blood of the victim was spilt at the altar, and the flesh consumed. One of these offerings implied a consciousness of sin in the offerer; and this sacrifice he brought as an atonement: the other implied a sense of mercies already received, and was offered in the way of gratitude.
David presents himself before the Lord with offerings of both kinds.
This prayer of the people is concluded with Selah, which we have taken up in the general sense of so be it. Hear and answer. It will and must be so, etc.
Verse 4
Grant thee according to thine own heart - May God give thee whatsoever thou art setting thy heart upon, and accomplish all thy desires! This was probably the prayer of the high priest.
Verse 5
We will rejoice in thy salvation - We expect help from thee alone; it is in thy cause we engage; and to thee, as our war is a just one, we consecrate our banners, inscribed with thy name. It is said that the Maccabees had their name from the inscription on their banners; which was taken from [Exo 15:11], מי כמכה באלם יהוה mi camochah baelim Yehovah, "Who is like unto thee, O Lord, among the gods?" The word being formed from the initial letters מ M, כ C, ב B, י I, מכבי Ma Ca B I, whence Maccabeus and Maccabees.
The words of this verse were spoken by David and his officers; immediately after which I suppose the high priest to have added, The Lord fulfill all thy petitions!
Verse 6
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.
Verse 7
Some trust in chariots - The words of the original are short and emphatic: These in chariots; and these in horses; but we will record in the name of Jehovah our God. Or, as the Septuagint, μεγαλυνθησομεθα, "we shall be magnified." Or, as the Vulgate, invocabimus, "we shall invoke the name of the Lord." This and the following verse I suppose to be the words of David and his officers. And the mention of chariots and horses makes it likely that the war with the Ammonites and Syrians is that to which reference is made here; for they came against him with vast multitudes of horsemen and chariots. See [2Sam 10:6-8]. According to the law, David could neither have chariots nor horses; and those who came against him with cavalry must have a very great advantage; but he saw that Jehovah his God was more than a match for all his foes, and in him he trusts with implicit confidence.
Verse 8
They are brought down and fallen - They were so confident of victory that they looked upon it as already gained. They who trusted in their horses and chariots are bowed down, and prostrated on the earth: they are all overthrown.
But we are risen - We who have trusted in the name of Jehovah are raised up from all despondency; and we stand upright - we shall conquer, and go on to conquer.
Verse 9
Save, Lord - This verse was spoken by all the congregation, and was the chorus and conclusion of the piece.
The verse may be read, Lord, save the king! He will hear as in the day of our calling. The Vulgate, Septuagint, Ethiopic, Arabic, Anglo-Saxon, read the verse thus: Lord, save the king! and hear us whensoever we shall call upon thee. The Syriac reads differently: The Lord will save us: and our king will hear us in the day in which we shall call upon him. This refers all to God: while the others refer the latter clause to David. Lord, save David; and David will save us. "If thou preservest him, he will be thy minister for good to us." This appears to be the easiest sense of the place, and harmonizes with all the rest.
Introduction
The psalmist returns thanks to God for giving him the victory over his enemies; which victory he had earnestly requested, [Psa 21:1], [Psa 21:2]. He enters into a detail of the blessings that in consequent of the victory he had obtained, [Psa 21:3-7]. He predicts the destruction of all those who may hereafter rise up against him, [Psa 21:8-12]; and concludes with praising the power of Jehovah, [Psa 21:13].
In the title of this Psalm there is nothing particularly worthy of remark. The occasion of it is variously understood. Some think it was composed to celebrate the victory obtained over Sennacherib; others, that it was made on the recovery of Hezekiah, and the grant of fifteen years of longer life; see [Psa 21:4]. Others and they with most appearance of propriety consider it a song of rejoicing composed by David for his victory over the Ammonites which ended in the capture of the royal city of Rabbah, the crown of whose king David put on his own head, see [Psa 21:3], and to procure which victory David offered the prayers and sacrifices mentioned in the preceding Psalm. Lastly, many think that it is to be wholly referred to the victories of the Messiah; and it must be owned that there are several expressions in it which apply better to our Lord than to David, or to any other person; and to him the Targum applies it, as does likewise my old Anglo-Scottish Psalter in paraphrasing the text.
Verse 1
The king shall joy - מלך משיחא melech Meshicha, "the King Messiah." - Targum. What a difference between ancient and modern heroes! The former acknowledged all to be of God, because they took care to have their quarrel rightly founded; the latter sing a Te Deum, pro forma, because they well know that their battle is not of the Lord. Their own vicious conduct sufficiently proves that they looked no higher than the arm of human strength. God suffers such for a time, but in the end he confounds and brings them to naught.
Verse 2
Thou hast given him his heart's desire - This seems to refer to the prayers offered in the preceding Psalm; see especially [Psa 21:1-4].
Verse 3
Thou preventest him - To prevent, from prcevenio, literally signifies to go before. Hence that prayer in the communion service of our public Liturgy, "Prevent us, O Lord, in all our doings, with thy most gracious favor!" That is, "Go before us in thy mercy, make our way plain, and enable us to perform what is right in thy sight!" And this sense of prevent is a literal version of the original word תקדמנו tekademennu. "For thou shalt go before him with the blessings of goodness."
Our ancestors used God before in this sense. So in Henry V.'s speech to the French herald previously to the battle of Agincourt: - "Go therefore; tell thy master, here I am.
My ransom is this frail and worthless trunk;
My army, but a weak and sickly guard:
Yet, God before, tell him we will come on,
Though France himself, and such another neighbor,
Stand in our way."
A crown of pure gold - Probably alluding to the crown of the king of Rabbah, which, on the taking of the city, David took and put on his own head. See the history, [2Sam 12:26-30] (note).
Verse 4
He asked life of thee - This verse has caused some interpreters to understand the Psalm of Hezekiah's sickness, recovery, and the promised addition to his life of fifteen years; but it may be more literally understood of the Messiah, of whom David was the type, and in several respects the representative.
Verse 5
His glory is great - But great as his glory was, it had its greatness from God's salvation. There is no true nobility but of the soul, and the soul has none but what it receives from the grace and salvation of God.
Verse 6
Thou hast made him most blessed for ever - Literally, "Thou hast set him for blessings for ever." Thou hast made the Messiah the Source whence all blessings for time and for eternity shall be derived. He is the Mediator between God and man.
Thou hast made him exceeding glad - Jesus, as Messiah, for the joy that was set before him, of redeeming a lost world by his death, endured the cross, and despised the shame, and is for ever set down on the right hand of God.
Verse 7
The king trusteth in the Lord - It was not by my skill or valor that I have gained this victory, but by faith in the strong protecting, and conquering arm of Jehovah.
He shall not be moved - Perhaps this may be best understood of him who was David's prototype. His throne, kingdom, and government, shall remain for ever.
