‏ Isaiah 52:3

3. As you became your foes' servants, without their paying any price for you (Jr 15:13), so they shall release you without demanding any price or reward (Is 45:13), (where Cyrus is represented as doing so: a type of their final restoration gratuitously in like manner). So the spiritual Israel, "sold under sin," gratuitously (Ro 7:14), shall be redeemed also gratuitously (Is 55:1).
