Unto thee, O my strength, will I sing - The source of strength to me; the real strength by which I have obtained deliverance is in thee. See the notes at Psalm 18:1.

For God is my defense - See the notes at Psalm 59:9.

And the God of my mercy - The God who has showed mercy to me; he from whom all these favors have sprung. Whatever means might be used to secure his own safety (compare 1 Samuel 19:12 ff) still he felt that his deliverance was to be traced wholly to God. He had interposed and had saved him; and it was proper, therefore, that praise should be ascribed to him. The experience of David in the case referred to in this psalm should be an inducement to all who are in danger to put their trust in God; his anticipated feelings of gratitude, and his purpose to praise God when he should be delivered, should awaken in us the resolution to ascribe to God all the praise when we are delivered from impending troubles, and when our lives are lengthened out where we have been in imminent danger. Whatever may have been the means of our rescue, it is to be traced to the interposition of God.

Unto thee, O my strength - A similar sentiment to that expressed, Psalm 59:9. But the words are very emphatic: God is my strength; God is my elevation. My God is my mercy. I have nothing good but what I have from God. And all springs from his dwelling in me. God, therefore, shall have all the glory, both now and for ever.

As many persons may still think that the inscription to this Psalm is correct, the following analysis may be applied in that way; or considered as containing a general resolution of the Psalm, without referring it to any particular occasion.

Unto thee, O my strength, will I sing,.... That is, to God, whom he made his strength, and put his trust in for strength, and from whom he received it; and he therefore determined to sing praise to him for it, and give him the glory of it;

for God is my defence: as before in Psalm 59:9;

and the God of my mercy; See Gill on Psalm 59:10.

Unto thee, O my {o} strength, will I sing: for God is my defence, and the God of my mercy.

(o) Confessing himself to be void of all virtue and strength, he attributes the whole to God.

59:8-17 It is our wisdom and duty, in times of danger and difficulty, to wait upon God; for he is our defence, in whom we shall be safe. It is very comfortable to us, in prayer, to look to God as the God of our mercy, the Author of all good in us, and the Giver of all good to us. The wicked can never be satisfied, which is the greatest misery in a poor condition. A contented man, if he has not what he would have, yet he does not quarrel with Providence, nor fret within himself. It is not poverty, but discontent that makes a man unhappy. David would praise God because he had many times, and all along, found Him his refuge in the day of trouble. He that is all this to us, is certainly worthy of our best affections, praises, and services. The trials of his people will end in joy and praise. When the night of affliction is over, they will sing of the Lord's power and mercy in the morning. Let believers now, in assured faith and hope, praise Him for those mercies, for which they will rejoice and praise him for ever.
