The LORD will perfect that which concerneth me: thy mercy, O LORD, endureth for ever: forsake not the works of thine own hands.
The Lord will perfect that which concerneth me. The fact that the work of salvation, begun in us, is the work of God, is a token of assurance that He "will perfect" it (Psalms 57:2; Isaiah 26:12; Philippians 1:6).
Thy mercy, O Lord, endureth forever - (Psalms 103:17; 2 Samuel 7:13; 2 Samuel 7:26.)
Forsake not the works of thine own hands - leave not incomplete the work of salvation for myself, my seed, and through it for my nation, and for the whole world. God had begun the work by delivering David from his enemies, and raising him to the throne.
