I will praise thee for ever, because thou hast done {h} it: and I will wait on thy name; for it is good before thy saints.

(h) Executed his vengeance.

Wesley's Notes

52:9 Thou hast - Destroyed mine and thine implacable enemies, and established me in the throne, of which I am no less assured, than if it were already done. I will continue in thy way, placing my whole confidence in thy power and goodness, and faithfulness. Before - In the presence of thy saints.

Jamieson-Fausset-Brown Bible Commentary

9. hast done-that is, what the context supplies, "preserved me" (compare Ps 22:31).

wait . name-hope in Thy perfections, manifested for my good (Ps 5:11; 20:1).

for it is good-that is, Thy name, and the whole method or result of its manifestation (Ps 54:6; 69:16).

Matthew Henry's Concise Commentary

52:6-9 Those wretchedly deceive themselves, who think to support themselves in power and wealth without God. The wicked man trusted in the abundance of his riches; he thought his wickedness would help him to keep his wealth. Right or wrong, he would get what he could, and keep what he had, and ruin any one that stood in his way; this he thought would strengthen him; but see what it comes to! Those who by faith and love dwell in the house of God, shall be like green olive-trees there. And that we may be as green olive-trees, we must live a life of faith and holy confidence in God and his grace. It adds much to the beauty of our profession, and to fruitfulness in every grace, to be much in praising God; and we never can want matter for praise. His name alone can be our refuge and strong tower. It is very good for us to wait on that saving name; there is nothing better to calm and quiet our spirits, when disturbed, and to keep us in the way of duty, when tempted to use any crooked courses for our relief, than to hope, and quietly wait for the salvation of the Lord. None ever followed his guidance but it ended well.
