Leviticus 25:40-42

Complete Jewish Bible

⁴⁰ Rather, you are to treat him like an employee or a tenant; he will work for you until the year of yovel. ⁴¹ Then he will leave you, he and his children with him, and return to his own family and regain possession of his ancestral land. ⁴² For they are my slaves, whom I brought out of the land of Egypt; therefore they are not to be sold as slaves.
