Leviticus 25:38-40

New Revised Standard Version, Anglicised Catholic Edition

³⁸ I am the Lord your God, who brought you out of the land of Egypt, to give you the land of Canaan, to be your God.

³⁹ If any who are dependent on you become so impoverished that they sell themselves to you, you shall not make them serve as slaves. ⁴⁰ They shall remain with you as hired or bound labourers. They shall serve with you until the year of the jubilee.
