Jeremiah 34:7 KJV

5But thou shalt die in peace: and with the burnings of thy fathers, the former kings which were before thee, so shall they burn odours for thee; and they will lament thee, saying, Ah lord! for I have pronounced the word, saith the LORD.

6Then Jeremiah the prophet spake all these words unto Zedekiah king of Judah in Jerusalem,

7When 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 defenced cities remained of the cities of Judah.

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

9That every man should let his manservant, and every man his maidservant, being an Hebrew or an Hebrewess, go free; that none should serve himself of them, to wit, of a Jew his brother.
