'Redeem Me' in the Bible

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

But God will redeem my life from the power of Sheol,For He will receive me. Selah.

Draw near to my soul and redeem it;Ransom me because of my enemies [so that they do not delight in my distress].

Plead my cause and redeem me;Revive me and give me life according to [the promise of] Your word.
