Deuteronomy 15:12-18

12If a fellow Hebrew, a man or a woman, is sold1 to you and serves you six years, then in the seventh year you must set him free.

13And when you release him, do not send him away empty-handed. 14You are to furnish him liberally from your flock, your threshing floor, and your winepress. You shall give to him as the LORD your God has blessed you. 15Remember that you were slaves 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 servant says to you, ‘I do not want to leave you,’ because he loves you and your household and is well off with you, 17then take an awl and pierce it through his ear into the door, and he will become your servant for life. And treat your maidservant the same way.

18Do not regard it as a hardship to set your servant free, because his six years of service were worth twice the wages of a hired hand. And the LORD your God will bless you in all you do.
