Yirmeyah 34:9-11

Orthodox Jewish Bible

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.

¹⁰ Now when all the sarim, and kol HaAm, which had entered into the brit (covenant), heard that every one should set free his eved, and every one his shifchah, that none should keep them in bondage, then they obeyed, and let them go.

¹¹ But afterward they changed their minds, and caused avadim and the shfakhot, whom they had set free, to return, and brought them into subjection for avadim and for shfakhot.
