Deuteronomy 15:12-18

12“1If your fellow countryman, a Hebrew man or woman, is sold to you, then he shall serve you for six years, but in the seventh year you shall set him 2free. 13And when you set him 3free, you shall not send him away empty-handed. 14You shall give generously to him from your flock, your threshing floor, and from your wine vat; you shall give to him as the Lord your God has blessed you. 15And you are to remember that you were a slave in the land of Egypt, and the Lord your God redeemed you; therefore I am commanding 4this of you today. 16But it shall come about, 5if he says to you, ‘I will not leave you,’ because he loves you and your household, since he is doing well with you, 17then you shall take an 6awl and pierce it through his ear into the door, and he shall be your servant permanently. You shall also do the same to your female slave.

18“It shall not seem difficult for you when you set him 7free, because he has given you six years with double the 8service of a hired worker; so the Lord your God will bless you in whatever you do.
