Charles Ellicott Commentary Psalms 71:4-6

"Rescue me, O my God, out of the hand of the wicked, Out of the hand of the unrighteous and cruel man. For thou art my hope, O Lord Jehovah: [Thou art] my trust from my youth. By thee have I been holden up from the womb; Thou art he that took me out of my mother`s bowels: My praise shall be continually of thee." — Psalms 71:4-6 (ASV)

These verses are manifestly founded on Psalms 31:8-10; but the variations are more marked than usual, and indicate a definite purpose of adaptation rather than copying.
