Deuteronomy 15:16

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

13 And when you release him, do not send him away empty-handed.

14 You 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.

15 Remember 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.

16 But 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,

17 then 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.

18 Do 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.

19 You must set apart to the LORD your God every firstborn male produced by your herds and flocks. You are not to put the firstborn of your oxen to work, nor are you to shear the firstborn of your flock.

20 Each year you and your household are to eat it before the LORD your God in the place the LORD will choose.
