Psalms 52:9

I will praise thee forever, beause thou hast done it -Because thou art the source of my safety. The fact that I have been delivered from the designs of Saul, and saved from the efforts of Doeg to betray me, is to be traced wholly to thee. It has been ordered by thy providence that the purposes alike of Doeg and of Saul have been defeated, and I am still safe. And I will wait on thy name -That is, I will wait on “thee;” the name being often put for the person himself:Psalms 20:1;Psalms 69:30;Proverbs 18:10;Isaiah 59:19. The language used here means that he would trust in God, or confide in him. All his expectation and hope would be in him.
