Psalms 52:9 - Matthew Poole's English Annotations on the Holy Bible

Because thou hast done it, i.e. destroyed Doeg, and all mine and thine implacable enemies, and established me in the throne, and in thy house; of which I am no less assured than if it were already done. I will wait on thy name; I will continue in thy way, placing my whole trust and confidence in thy power, and goodness, and faithfulness, all which are called God's name, and not turn aside to any crooked paths for my deliverance, as others do, Psalms 125:5. Before thy saints, i.e. in the eyes of thy saints. They, whose judgments only are to be valued, approve of this practice, of trusting God and keeping his way, as the wisest and safest course, and have ever found it so to be by their own experience, however Doeg and his accomplices account it mere folly, and the ready way to ruin. But the last words of this clause may very conveniently be joined with the former clause, thus, I will wait upon thy name before thy saints; which seems best to suit with the first clause, I will praise thee; which surely was meant of praising God publicly, or before the saints; and then it follows conveniently. And in the mean time I will wait on thy name, in the presence of thy saints, who shall plainly see that I do so by the whole course of my life. And those words, for it is good, may be enclosed within a parenthesis, as is very usual in Scripture, and may be referred, either to God's name, for thy name is good; or to wait on it, for it is good to wait upon it.
