Jeremiah 34:7-11

YLT(i) 7 and the forces of the king of Babylon are fighting against Jerusalem, and against all the cities of Judah that are left—against Lachish, and against Azekah, for these have been left among the cities of Judah, cities of fortresses.
8 The word that hath been unto Jeremiah from Jehovah, after the making by the king Zedekiah of a covenant with all the people who are in Jerusalem, to proclaim to them liberty, 9 to send out each his man-servant, and each his maid-servant—the Hebrew and the Hebrewess—free, so as not to lay service on them, any on a Jew his brother; 10 and hearken do all the heads, and all the people who have come in to the covenant to send forth each his man-servant and each his maid-servant free, so as not to lay service on them any more, yea, they hearken, and send them away; 11 and they turn afterwards, and cause the men-servants and the maid-servants to return, whom they had sent forth free, and they subdue them for men-servants and for maid-servants.
