Leviticus 25:29-36

²⁹And if a man sell a dwelling-house in a walled city, then he may redeem it within a whole year after it is sold; for a full year shall he have the right of redemption.

³⁰And if it be not redeemed within the space of a full year, then the house that is in the walled city shall be made sure in perpetuity to him that bought it, throughout his generations; it shall not go out in the jubilee.

³¹But the houses of the villages which have no wall round about them shall be reckoned with the fields of the country; they may be redeemed, and they shall go out in the jubilee.

³²But as for the cities of the Levites, the houses of the cities of their possession, the Levites shall have a perpetual right of redemption.

³³And if a man purchase of the Levites, then the house that was sold in the city of his possession, shall go out in the jubilee; for the houses of the cities of the Levites are their possession among the children of Israel.

³⁴But the fields of the open land about their cities may not be sold; for that is their perpetual possession.

³⁵And if thy brother be waxen poor, and his means fail with thee; then thou shalt uphold him: as a stranger and a settler shall he live with thee.

³⁶Take thou no interest of him or increase; but fear thy God; that thy brother may live with thee.
