Jeremiah 34:8-11

ASV(i) 8 The word that came unto Jeremiah from Jehovah, after that the king Zedekiah had made a covenant with all the people that were at Jerusalem, to proclaim liberty unto them; 9 that every man should let his man-servant, and every man his maid-servant, that is a Hebrew or a Hebrewess, go free; that none should make bondmen of them, [to wit], of a Jew his brother. 10 And all the princes and all the people obeyed, that had entered into the covenant, that every one should let his man-servant, and every one his maid-servant, go free, that none should make bondmen of them any more; they obeyed, and let them go: 11 but afterwards they turned, and caused the servants and the handmaids, whom they had let go free, to return, and brought them into subjection for servants and for handmaids.
