Deuteronomy 15
12 Ref If your brother, a Hebrew man, or a Hebrew woman, be sold to you, and serve you six years; then in the seventh year you shall let him go free from you.
13 Ref When you let him go free from you, you shall not let him go empty:
14 Ref you shall furnish him liberally out of your flock, and out of your threshing floor, and out of your winepress; as Yahweh your God has blessed you, you shall give to him.
15 Ref You shall remember that you were a bondservant in the land of Egypt, and Yahweh your God redeemed you: therefore I command you this thing today.
16 Ref It shall be, if he tell you, I will not go out from you; because he loves you and your house, because he is well with you;
17 Ref then you shall take an awl, and thrust it through his ear to the door, and he shall be your servant forever. Also to your maid-servant you shall do likewise.
18 Ref It shall not seem hard to you, when you let him go free from you; for to the double of the hire of a hireling has he served you six years: and Yahweh your God will bless you in all that you do.
