Leviticus 25:35-42

35“ ‘If any of your fellow Israelites become poor and are unable to support themselves among you, help them as you would a foreigner and stranger, so they can continue to live among you. 36Do not take interest or any profit from them, but fear your God, so that they may continue to live among you. 37You must not lend them money at interest or sell them food at a profit.

38I am the LORD your God, who brought you out of Egypt to give you the land of Canaan and to be your God. 39“ ‘If any of your fellow Israelites become poor and sell themselves to you, do not make them work as slaves. 40They are to be treated as hired workers or temporary residents among you; they are to work for you until the Year of Jubilee. 41Then they and their children are to be released, and they will go back to their own clans and to the property of their ancestors. 42Because the Israelites are my servants, whom I brought out of Egypt, they must not be sold as slaves.
