Deuteronomy 15:12-18

12“If your fellow Hebrew, a man or woman, is sold to you and serves you six years, you must set him free in the seventh year.

13When you set him free, do not send him away empty-handed.

14Give generously to him from your flock, your threshing floor, and your winepress. You are to give him whatever the Lord your God has blessed you with.

15Remember that you were a slave in the land of Egypt and the Lord your God redeemed you; that is why I am giving you this command today.

16But if your slave says to you, ‘I don’t want to leave you,’ because he loves you and your family, and is well off with you,

17take an awl and pierce through his ear into the door, and he will become your slave for life. Also treat your female slave the same way.

18Do not regard it as a hardship when you set him free, because he worked for you six years — worth twice the wages of a hired worker. Then the Lord your God will bless you in everything you do.
