Deuteronomy 15:16-18

New Catholic Bible

¹⁶ But if your slave says to you, “I do not want to leave you,” because he loves you and your family and is well off with you, ¹⁷ then take an awl and push it through his ear lobe into the door. He will then be your slave forever. You are to do the same with your maidservants as well. ¹⁸ Do not consider it to be a hardship to set your slave free. You received twice as much from him in the six years as you would have from a hired hand, and the Lord, your God, will bless you in all of your undertakings.
