Jer 34:16

וַתָּשֻׁ֨בוּ֙ וַתְּחַלְּל֣וּ אֶת־שְׁמִ֔י וַתָּשִׁ֗בוּ אִ֤ישׁ אֶת־עַבְדּוֹ֙ וְאִ֣ישׁ אֶת־שִׁפְחָת֔וֹ אֲשֶׁר־שִׁלַּחְתֶּ֥ם חָפְשִׁ֖ים לְנַפְשָׁ֑ם וַתִּכְבְּשׁ֣וּ אֹתָ֔ם לִֽהְי֣וֹת לָכֶ֔ם לַעֲבָדִ֖ים וְלִשְׁפָחֽוֹת׃ ס

But now you have changed your minds and profaned My name. Each of you has taken back the menservants and maidservants whom you had set at liberty to go wherever they wanted, and you have again forced them to be your slaves.
