Verse 21. - Let integrity and uprightness preserve me. Scarcely his own inherent integrity and uprightness, the want of which he has deplored when confessing that his iniquity is great (ver. 11). Rather an integrity and uprightness whereto he hopes to attain, by the grace of God, in days to come - an integrity and uprightness for which he "waits" For I wait on thee.

25:15-22 The psalmist concludes, as he began, with expressing dependence upon God, and desire toward him. It is good thus to hope, and quietly to wait for the salvation of the Lord. And if God turns to us, no matter who turns from us. He pleads his own integrity. Though guilty before God, yet, as to his enemies, he had the testimony of conscience that he had done them no wrong. God would, at length, give Israel rest from all their enemies round about. In heaven, God's Israel will be perfectly redeemed from all troubles. Blessed Saviour, thou hast graciously taught us that without thee we can do nothing. Do thou teach us how to pray, how to appear before thee in the way which thou shalt choose, and how to lift up our whole hearts and desires after thee, for thou art the Lord our righteousness.Let integrity and uprightness preserve me,.... Meaning either his own, as in Psalm 7:8; and then the sense is, either that God would preserve him, seeing he had acted the faithful and upright part in the government of the people of Israel, and they had rebelled against him without a cause; see Psalm 78:72; or that those might be continued with him, that he might not be led aside by the corruptions of his heart, and the temptations of Satan, and by the provocations of his rebellious subjects, to act a part disagreeable to his character, as a man of integrity and uprightness; but that these remaining with him, might be a means of keeping him in the ways of God, Proverbs 13:6; or else the integrity and uprightness of God are designed, which are no other than his goodness and grace to his people, and his faithfulness in his covenant and promises, or his lovingkindness and his truth; see Psalm 40:11;

for I wait on thee: in the use of means for deliverance and safety; the Targum is, "for I trust in thy word".
