For thus saith the LORD, Ye have sold yourselves for nought; and ye shall be redeemed without money.
Ye have sold yourselves for nought; and ye shall be redeemed without money - As you became your foes' servants, without their paying any price for you (Jeremiah 15:13), so they shall release you without demanding any price or reward: cf. Isaiah 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 (Romans 7:14), shall be redeemed also gratuitously (Isaiah 55:1).
