Jeremiah 34:9

that every man should let his male servant, and every man his female servant, who is a Hebrew or a Hebrewess, go free; that none should make bondservants of them, of a Jew his brother.

That 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.
