Deliverance by purchase

And so the New Testament proclamation of redemption in and by Jesus Christ carries forward two major Old Testament themes. Redemption continues to mean liberation by a mighty power, as in some of the postexilic portions of the Old Testament; and second, it continues to bear its original Old Testament meaning of a price paid. Hence, again, the meaning is deliverance by purchase at cost, allowing for considerable movement between the two.—Fleming Rutledge, The Crucifixion, 293 (emphasis original)
