Yirmeyah 34:7-9

Orthodox Jewish Bible

⁷ When the army of Melech Bavel fought against Yerushalayim, and against all the towns of Yehudah that were left, against Lachish, and against Azekah; for these fortified cities remained of the cities of Yehudah.

⁸ This is the Davar that came unto Yirmeyah from Hashem, after that Tzidkiyah HaMelech had cut a Brit with kol HaAm which were at Yerushalayim, to proclaim deror (liberty) unto them;

⁹ That every ish should set free his eved, and every ish his shifchah, being Ivri (Hebrew man) or Ivriyah (Hebrew woman); that none should hold another brother Yehudi in bondage.
