Psalms 21:4

Clarke's Commentary

Verse Psalms 21:4. 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.

Bridgeway Bible Commentary

Psalms 20-21 Before and after battle

These two psalms belong together as a pair. The former is a prayer for the king before he leads the people in battle; the latter, a thanksgiving after victory.
Addressing the king, the people call down God’s power and protection upon him (20:1-2). They pray that God will remember the king’s faithfulness and give him victory (3-5). The king replies that victory is certain, because he has God’s help. God’s power is greater than military might (6-8). In response, the people offer a further plea, brief and urgent, for God’s help (9).

The people join in thanksgiving to God that he has answered their prayer of the previous psalms (see Psalms 20:4). God has given the king his heart’s desire, enabling him to lead his people to victory (21:1-4). Although the king receives glory because of his victory, the glory is not self-centred. It is glory given him by God, in whom he trusts (5-7). Having offered thanks to God, the people turn and address the king. They assure him that through God’s power he will continue to have victory over all his enemies (8-12). King and people then unite in praise to God (13).

Coffman's Commentaries on the Bible

“For thou meetest him with the blessings of goodness: Thou settest a crown of fine gold on his head. He asked life of thee, thou gavest it him, Even length of days forever and ever.”

“A crown of fine gold” (Psalms 21:3). This indeed applies to David; but such a crown merely symbolized the golden crown of Revelation 14:14 and the many crowns of Revelation 19:12.

“Even length of days forever and ever” (Psalms 21:4). As Barnes noted, David had merely asked for life, but God gave him far more than he requested. “It is by no means an uncommon thing that God gives us more than we ask in our prayers.”Barnes’ Notes on the Old Testament (Grand Rapids: Baker Book House, a 1987 reprint of the 1878 edition), p. 1841.

“Forever and ever” (Psalms 21:4). It is distressing to us that even some of our brethren are willing to view these words merely as the equivalent of a common expression in that period of time, such as “O, King live forever.” “There is considerable probability that the words from this Psalm, as well as in Proverbs 12:28, mean eternal life.”Mitchell Dahood in The Anchor Bible, p. 132. Furthermore, although Maclaren freely admitted such expressions as, “O King live forever,” are in a sense parallel to what is said here, “The great emphasis of expression here and its repetition in Psalms 21:6 (immediately following) can scarcely be disposed of as mere hyperbole.” Also, as both Maclaren and Dahood pointed out Divine attributes are also ascribed to “the King” of this passage in Psalms 21:6, thus clearly distinguishing the earthly king David from the glorious “Son of David” introduced in the first verse of the New Testament.

Barnes' Notes on the Whole Bible

He asked life of thee - An expression similar to this occurs in Psalms 61:5-6, “For thou, O God, hast heard my vows;...Thou wilt prolong the king’s life, and his years to many generations.” The expression in both cases implies that there had been a prayer for “life,” as if life were in danger. The expression itself would be applicable to a time of sickness, or to danger of any kind, and here it is used doubtless in reference to the exposure of life in going into battle, or in going forth to war. In this apprehended peril he prayed that God would defend him. He earnestly sought protection as he went forth to the perils of war.

And thou gavest it him - Thou didst hear and answer his prayer. He was saved from danger.

Even length of days forever and ever - Thou didst grant him more than he asked. He sought life for himself; thou bast not only granted that, but hast granted to him the assurance that he should live in his posterity to all generations. The idea is, that there would be an indefinite contination of his race. His posterity would occupy his throne, and there would be no end to his reign thus prolonged. Beyond all his petitions and his hopes, God bad given the assurance that his reign would be permanent and enduring. We cannot suppose that he understood this as if it were a promise made to him personally, that “he” would live and would occupy the throne forever; but the natural interpretation is that which would refer it to his posterity, and to the perpetuity of the reign of his family or descendants. A similar promise occurs elsewhere: 2 Samuel 7:13, 2 Samuel 7:16; compare the notes at Psalms 18:50. It is by no means an uncommon thing that God gives us more than we asked in our prayers. The offering of prayer is not only the means of securing the blessing which we asked, but also often of securing much more important blessings which we did not ask. If the expression were allowable it might be said that the prayer “suggested” to the divine mind the conferring of all needed blessings, or it indicates such a state of mind on the part of him who prays that God “takes occasion” to confer blessings which were not asked; as a request made by a child to a parent for a specific favor is followed not only by granting “that” favor, but by bestowing others of which the child did not think. The state of mind on the part of the child was such as to “dispose” the parent to grant much larger blessings.

Calvin's Commentary on the Bible

4.He asked life from thee. This verse confirms what I have formerly said, that this psalm is not to be limited to the person of any one man. David’s life, it is true, was prolonged to an advanced period, so that, when he departed from this world, he was an old man, and full of days; but the course of his life was too short to be compared to this length of days, which is said to consist of many ages. Even if we reckon the time from the commencement of David’s reign to the captivity of Babylon, this length of days will not be made up and completed in all David’s successors. David, therefore, without doubt, comprehends the Eternal King. There is here a tacit comparison between the beginnings of this kingdom, which were obscure and contemptible, or rather which were fraught with the most grievous perils, and which bordered on despair; and the incredible glory which followed, when God, exempting it from the common lot of other kingdoms, elevated it almost above the heavens. For it is no ordinary commendation of this kingdom, when it is said, that it shall endure as long as the sun and moon shall shine in the heavens, (Psalms 72:1.) David, therefore, in saying that he asked life, tacitly points to the distressed circumstances to which he had often been reduced; and the meaning is, Lord, since the time thou hast called thy servant to the hope of the kingdom by thy holy anointing, his condition has been such that he has accounted it a singular blessing to be rescued from the jaws of death; but now, he has not only, by thy grace, escaped in safety the dangers which threatened his life: thou hast also promised that his kingdom will be continued for many ages in his successors. And it serves not a little to magnify the grace of God, that he vouchsafed to confer on a poor and miserable man, who was almost at the point of death, not only his life, - when, amidst the dangers which threatened it, he tremblingly asked merely its preservations — but also the inestimable honor of elevating him to the royal dignity, and of transmitting the kingdom to his posterity for ever. Some expound the verse thus:— Thou hast given him the life which he asked, even to the prolonging of his days for ever and ever. But this seems to me a cold and strained interpretation. We must keep in view the contrast which, as I have said, is here made between the weak and contemptible beginnings of the kingdom, and the unexpected honor which God conferred upon his servant, in calling the moon to witness that his seed should never fail. The same has been exemplified in Christ, who, from contempt, ignominy, death, the grave, and despair, was raised up by his Father to the sovereignty of heaven, to sit at the Father’s right hand for ever, and at length to be the judge of the world.

Smith's Bible Commentary

Psalms 21:1-13

Again, to the chief musician, the psalm of David.

The king shall joy in thy strength, O LORD; and in thy salvation how greatly shall he rejoice! Thou hast given him his heart's desire, and you have not withheld the requests of his lips ( Psalms 21:1-2 ).

Now the Selah indicates, really, sort of a change of thought. It sort of introduces a new idea. It is just sort of a rest, and then introducing of a new idea, new thought pattern.

For you prevent him with the blessings of goodness: you set a crown of pure gold on his head. He asks for life from thee, and you gave it to him, even the length of days for ever and ever. His glory is great in thy salvation ( Psalms 21:3-5 ):

He is talking about the king's delight in the Lord, and how he was just so gracious for what God has done.

For thou hast made him most blessed for ever: thou hast made him exceeding glad with thy countenance. For the king trusts in the LORD, and through the mercy of the Most High he shall not be moved. Your hand shall find out all your enemies: your right hand shall find out those that hate thee. You will make them as a fiery oven in the time of thine anger: the LORD will swallow them up in his wrath, and the fire shall devour them. Their fruit will you destroy from the earth, and their seed from among the children of men. For they intended evil against thee: they imagined mischievous devices, that they are not able to perform. Therefore thou shalt make them to turn their back, when thou shalt make ready your arrows upon thy strings against the face of them. Be thou exalted, LORD, in your own strength: so will we sing of thy praise and thy power ( Psalms 21:5-13 ). "

Dr. Constable's Expository Notes

Speaking of himself in the third person, King David gave thanks to God for giving him victory over another king and his kingdom. He acknowledged that it was the Lord’s strength, not his own, that had brought him salvation in the battle. God had given David victory as a gift. The crown (Psalms 21:3) may refer to the literal crown of his enemy that victorious kings appropriated for themselves in David’s time. Metaphorically it could refer to a fresh coronation that David believed he had received from the Lord by granting him this victory. David’s life was safe, and much glory and joy had come to him as a result of the victory.

Dr. Constable's Expository Notes

1. Joy in God’s strength 21:1-7

Dr. Constable's Expository Notes

Psalms 21

This royal psalm of thanksgiving is a companion to the preceding one in that it records David’s thanksgiving for the victory that he anticipated in Psalms 20.

Gill's Exposition of the Whole Bible

He asked life of thee, [and] thou gavest [it] him,.... Both for himself, as man, when he was about to die, that he might be raised to life again, which was granted him; and for his people, that they might live spiritually and eternally, and accordingly life is given to him for them; and he has power to give it to as many as the Father has given him, John 17:2;

[even] length of days for ever and ever; the life he has for himself as man is what will ever continue; he will die no more, death will have no more dominion over him; he will live for evermore, and that to make intercession for his members, Romans 6:9; and the life which is granted them at his request is an everlasting one, both as to body and soul; for though they die as other men, they shall live again in the resurrection of the just, and never die more, but shall be like the angels in heaven; and as for the second death, that shall not harm them, nor have any power over them; they will live and reign with Christ for ever.

Henry's Complete Commentary on the Bible

To the chief musician. A psalm of David.

      1 The king shall joy in thy strength, O LORD; and in thy salvation how greatly shall he rejoice!   2 Thou hast given him his heart's desire, and hast not withholden the request of his lips. Selah.   3 For thou preventest him with the blessings of goodness: thou settest a crown of pure gold on his head.   4 He asked life of thee, and thou gavest it him, even length of days for ever and ever.   5 His glory is great in thy salvation: honour and majesty hast thou laid upon him.   6 For thou hast made him most blessed for ever: thou hast made him exceeding glad with thy countenance.

      David here speaks for himself in the first place, professing that his joy was in God's strength and in his salvation, and not in the strength or success of his armies. He also directs his subjects herein to rejoice with him, and to give God all the glory of the victories he had obtained; and all with an eye to Christ, of whose triumphs over the powers of darkness David's victories were but shadows. 1. They here congratulate the king on his joys and concur with him in them (Psalms 21:1; Psalms 21:1): "The king rejoices, he uses to rejoice in thy strength, and so do we; what pleases the king pleases us," 2 Samuel 3:36. Happy the people the character of whose king it is that he makes God's strength his confidence and God's salvation his joy, that is pleased with all the advancements of God's kingdom and trusts God to bear him out in all he does for the service of it. Our Lord Jesus, in his great undertaking, relied upon help from heaven, and pleased himself with the prospect of that great salvation which he was thereby to work out. 2. They gave God all the praise of those things which were the matter of their king's rejoicing. (1.) That God had heard his prayers (Psalms 21:2; Psalms 21:2): Thou hast given him his heart's desire (and there is no prayer accepted but what is the heart's desire), the very thing they begged of God for him, Psalms 20:4. Note, God's gracious returns of prayer do, in a special manner, require our humble returns of praise. When God gives to Christ the heathen for his inheritance, gives him to see his seed, and accepts his intercession for all believers, he give him his heart's desire. (2.) That God had surprised him with favours, and much outdone his expectations (Psalms 21:3; Psalms 21:3): Thou preventest him with the blessings of goodness. All our blessings are blessings of goodness, and are owing, not at all to any merit of ours, but purely and only to God's goodness. But the psalmist here reckons it in a special manner obliging that these blessings were given in a preventing way; this fixed his eye, enlarged his soul, and endeared his God, as one expresses it. When God's blessings come sooner and prove richer than we imagine, when they are given before we prayed for them, before we were ready for them, nay, when we feared the contrary, then it may be truly said that he prevented us with them. Nothing indeed prevented Christ, but to mankind never was any favour more preventing than our redemption by Christ and all the blessed fruits of his mediation. (3.) That God had advanced him to the highest honour and the most extensive power: "Thou hast set a crown of pure gold upon his head and kept it there, when his enemies attempted to throw it off." Note, Crowns are at God's disposal; no head wears them but God sets them there, whether in judgment to his land or for mercy the event will show. On the head of Christ God never set a crown of gold, but of thorns first, and then of glory. (4.) That God had assured him of the perpetuity of his kingdom, and therein had done more for him than he was able either to ask or think (Psalms 21:4; Psalms 21:4): "When he went forth upon a perilous expedition he asked his life of thee, which he then put into his hand, and thou not only gavest him that, but withal gavest him length of days for ever and ever, didst not only prolong his life far beyond his expectation, but didst assure him of a blessed immortality in a future state and of the continuance of his kingdom in the Messiah that should come of his loins." See how God's grants often exceed our petitions and hopes, and infer thence how rich he is in mercy to those that call upon him. See also and rejoice in the length of the days of Christ's kingdom. He was dead, indeed, that we might live through him; but he is alive, and lives for evermore, and of the increase of his government and peace there shall be no end; and because he thus lives we shall thus live also. (5.) That God had advanced him to the highest honour and dignity (Psalms 21:5; Psalms 21:5): "His glory is great, far transcending that of all the neighbouring princes, in the salvation thou hast wrought for him and by him." The glory which every good man is ambitious of is to see the salvation of the Lord. Honour and majesty hast thou laid upon him, as a burden which he must bear, as a charge which he must account for. Jesus Christ received from God the Father honour and glory (2 Peter 1:17), the glory which he had with him before the worlds were, John 17:5. And on him is laid the charge of universal government and to him all power in heaven and earth is committed. (6.) That God had given him the satisfaction of being the channel of all bliss to mankind (Psalms 21:6; Psalms 21:6): "Thou hast set him to be blessings for ever" (so the margin reads it), "thou hast made him to be a universal blessing to the world, in whom the families of the earth are, and shall be blessed; and so thou hast made him exceedingly glad with the countenance thou hast given to his undertaking and to him in the prosecution of it." See how the spirit of prophecy gradually rises here to that which is peculiar to Christ, for none besides is blessed for ever, much less a blessing for ever to that eminency that the expression denotes: and of him it is said that God made him full of joy with his countenance.

      In singing this we should rejoice in his joy and triumph in his exaltation.
