Let integrity and uprightness preserve me; for I wait on thee.
Integrity - i:e., not that a man's own "integrity" saves him; but it is the evidence of God's grace in him, and pleasing to God, so that we may be sure God will "preserve" such a one. God's part is expressed in Psalms 40:11, "Let THY loving-kindness and THY truth continually preserve me."
