Deuteronomy 15:16-19 New American Bible, Revised Edition (NABRE)

16. But if he says to you, “I do not wish to leave you,” because he loves you and your household, since he is well off with you,

17. you shall take an awl and put it through his ear into the door, and he shall be your slave forever. Your female slave, also, you shall treat in the same way.

18. Do not be reluctant when you let them go free, since the service they have given you for six years was worth twice a hired laborer’s salary; and the Lord, your God, will bless you in everything you do.

19. You shall consecrate to the Lord, your God, every male firstling born in your herd and in your flock. You shall not work the firstlings of your cattle, nor shear the firstlings of your flock.
