'Redeem Me' in the Bible

Or, ‘Deliver me from the hand of the adversary,’Or, ‘Redeem me from the hand of the tyrants’?

But as for me, I shall walk in my integrity;Redeem me, and be gracious to me.

Redeem me from the oppression of man,That I may keep Your precepts.

Plead my cause and redeem me;Revive me according to Your word.
