Jeremiah 34:8 WBT

⁶  Then Jeremiah the prophet spoke all these words to Zedekiah king of Judah in Jerusalem,

⁷  When the king of Babylon's army fought against Jerusalem, and against all the cities of Judah that were left, against Lachish, and against Azekah: for these fortified cities remained of the cities of Judah.

⁸  [This is] the word that came to Jeremiah from the LORD, after king Zedekiah had made a covenant with all the people who [were] at Jerusalem, to proclaim liberty to them;

⁹  That every man should liberate his man-servant, and every man his maid-servant, [being] a Hebrew or a Hebrewess; that none should retain them in service, [to wit], a Jew his brother.

¹⁰  Now when all the princes, and all the people who had entered into the covenant, heard that every one should liberate his man-servant, and every one his maid-servant, that none should retain them in service any more, then they obeyed, and let [them] go.
