'Redeemed' in the Bible

Therefore say to the sons of Israel, I am Jehovah, and I have brought you out from under the burdens of the Egyptians, and have delivered you from their service, and have redeemed you by a stretched-out arm, and by great judgments,

Thou in thy mercy hast led forth the people which thou hast redeemed: thou hast guided them in thy strength unto thy holy habitation.

If she please not her master, who hath betrothed her to himself, then shall he let her be redeemed: to sell her unto a strange nation he shall have no power, seeing he hath dealt deceitfully with her.
