Leviticus 25:40-42

New Revised Standard Version, Anglicised Catholic Edition

⁴⁰ They shall remain with you as hired or bound labourers. They shall serve with you until the year of the jubilee. ⁴¹ Then they and their children with them shall be free from your authority; they shall go back to their own family and return to their ancestral property. ⁴² For they are my servants, whom I brought out of the land of Egypt; they shall not be sold as slaves are sold.
