Leviticus 25:33-40

³³If one of the Levites does not redeem a house he sold, then the house that was sold in the city where it is located must be returned in the year of Jubilee, for the houses of the cities of the Levites are their property among the people of Israel.

³⁴But the fields around their cities may not be sold because they are the permanent property of the Levites.

³⁵If your fellow countryman becomes poor, so that he can no longer provide for himself, then you must help him as you would help a foreigner or anyone else living as an outsider among you.

³⁶Do not charge him interest or try to profit from him in any way, but honor your God so that your brother may keep living with you.

³⁷You must not give him a loan of money and charge interest, nor sell him your food to earn a profit.

³⁸I am Yahweh your God, who brought you out of the land of Egypt, in order that I might give you the land of Canaan, and that I might be your God.

³⁹If your fellow countryman has become poor and sells himself to you, you must not make him work like a slave.

⁴⁰Treat him as a hired servant. He must be like someone living temporarily with you. He will serve with you until the year of Jubilee.
