Jeremiah 34:15-16

15Now you had repented, and had done that which is right in My eyes, by proclaiming liberty everyone to his neighbor. You even had made a covenant before Me in the House where My Name is called.

16But you turned around and profaned My Name, and made everyone his servant and his handmaid, whom you had let go free at their will, return, and you brought them back into subjection, to be your servants and handmaids.”
