The Lord will perfect that which concerneth me; i.e. will complete what he has begun for me—will not leave his work unfinished (comp. Psalms 57:2; Philippians 1:6). Thy mercy, O Lord, endureth forever. Does not suddenly break off and stop. Forsake not the works of thine own hands. This is probably more than a mere personal request. David sees in God's care for himself a portion of his great providential scheme for the redemption of the world.
