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.
