Verse 16. - But I will sing of thy power; rather, of thy strength - the same word as that used in vers. 9 and 17. Yea, I will sing aloud of thy mercy in the morning. When the morning came, David had escaped (1 Samuel 19:12), and could "sing of God's mercy" securely at Ramah, where he had joined Samuel. For thou hast been my Defense and Refuge in the day of my trouble; or, my High Tower, as in vers. 9 and 17.

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.But I will sing of thy power,.... In creating all things out of nothing; in upholding all things in being; in the redemption of his people; in their conversion and calling; in the preservation of them to eternal happiness; in the performance of his promises to them; in the destruction of their enemies; and in their protection:

yea, I will sing aloud of thy mercy in the morning; of providential mercies, which are new every morning; and of special mercy in the heart of God, in the covenant of his grace, in redemption, in regeneration, in the pardon of sin, and in eternal life and salvation;

for thou hast been my defence; See Gill on Psalm 59:9;

and refuge in the day of my trouble; whither he fled, and found protection and safety; See Gill on Psalm 9:9.
