Verse 17. - Unto thee, O my Strength, will I sing: for God is my Defense; or, Strong Tower (comp. ver. 9, which, if we read עזּי for עזו, is so far, excepting in the verb, identical). And the God of my mercy; i.e. "the God who showeth mercy upon me" (comp. ver. 10).

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.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.
