Deuteronomy 15:13

9 Be careful not to harbor this wicked thought in your heart: “The seventh year, the year of release, is near,” so that you look upon your poor brother begrudgingly and give him nothing. He will cry out to the LORD against you, and you will be guilty of sin.

10 Give generously to him, and do not let your heart be grieved when you do so. And because of this the LORD your God will bless you in all your work and in everything to which you put your hand.

11 For there will never cease to be poor in the land; that is why I am commanding you to open wide your hand to your brother and to the poor and needy in your land.

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.
