Leviticus 25:29-35

²⁹And if a man sell a dwelling house in a town surrounded with a wall, he may redeem it within the full year of the sale of it; within that time shall be its redemption.

³⁰But if it be not repurchased when the whole year is completed, the house that is in the walled town shall belong absolutely to him who bought it for his generations; it shall not go out at the Jubilee.

³¹But the houses of the villages which have no wall round about them shall be accounted as the field of the land; they may be redeemed, or shall go out at the Jubilee.

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.
