'Redeem' in the Bible

But we were hoping that it was He who was going to redeem Israel and set our nation free. Indeed, besides all this, it is the third day since these things happened.

so that He might redeem and liberate those who were under the Law, that we [who believe] might be adopted as sons [as God’s children with all rights as fully grown members of a family].

who [willingly] gave Himself [to be crucified] on our behalf to redeem us and purchase our freedom from all wickedness, and to purify for Himself a chosen and very special people to be His own possession, who are enthusiastic for doing what is good.
