Leviticus 25:32-38

³²And the cities of the Levites, the houses of the cities of their inheritance, may be always redeemed by the Levites (or, be a perpetual redemption for the Levites).

³³And (so of him) who purchaseth of the Levites, the purchased house in the city of their possession shall go out at the Jubilee; for the houses of the cities of the Levites are their inheritance among the sons of Israel.

³⁴But a field in the suburbs of their cities may not be sold; for it is an everlasting possession for them.

³⁵And if thy brother hath become poor, and his band waver with thee, then thou shalt strengthen him, and he shall be a guest and a sojourner with thee.

³⁶Thou shalt not take from him any usuries, nor interest (increase), but shalt fear thy God, and let thy brother live with thee.

³⁷Thou shalt not give him thy money for usury, nor thy food for increase.

³⁸I am the Lord your God, who brought you out from the land of Mizraim, to give you the land of Kenaan, and to be your God.
