Leviticus 25:31-37

³¹But the houses of the villages which have no wall around them shall be accounted for with the fields of the country: they may be redeemed, and they shall be released in the Jubilee.

³²“‘Nevertheless, in the cities of the Levites, the Levites may redeem the houses in the cities of their possession at any time.

³³The Levites may redeem the house that was sold, and the city of his possession, and it shall be released in the Jubilee; for the houses of the cities of the Levites are their possession among the children of Israel.

³⁴But the field of the pasture lands of their cities may not be sold, for it is their perpetual possession.

³⁵“‘If your brother has become poor, and his hand can’t support himself among you, then you shall uphold him. He shall live with you like an alien and a temporary resident.

³⁶Take no interest from him or profit; but fear your God, that your brother may live among you.

³⁷You shall not lend him your money at interest, nor give him your food for profit.
