Leviticus 25:23-34

²³‘The land, moreover, shall not be sold permanently, because the land is Mine; for you are only strangers and residents with Me. ²⁴So for every piece of your property, you are to provide for the redemption of the land.

²⁵‘If a fellow countryman of yours becomes so poor that he sells part of his property, then his closest redeemer is to come and buy back what his relative has sold. ²⁶Or in case someone has no redeemer, but recovers to find sufficient means for its redemption, ²⁷then he shall calculate the years since its sale and refund the balance to the man to whom he sold it, and so return to his property. ²⁸But if he has not found sufficient means to get it back for himself, then what he has sold shall remain in the hands of its purchaser until the year of jubilee; but at the jubilee it shall revert, so that he may return to his property.

²⁹‘Likewise, if a man sells a dwelling house in a walled city, then his redemption right remains valid until a full year after its sale; his right of redemption lasts a full year. ³⁰But if it is not bought back for him within the space of a full year, then the house that is in the walled city passes permanently to its purchaser throughout his generations; it does not revert in the jubilee. ³¹The houses of the villages, however, which have no surrounding wall, shall be regarded as open fields; they have redemption rights and revert in the jubilee. ³²As for the cities of the Levites, the Levites have a permanent right of redemption for the houses of the cities which are their possession. ³³What, therefore, belongs to the Levites may be redeemed, and a house sale in the city of this possession reverts in the jubilee, because the houses of the cities of the Levites are their possession among the sons of Israel. ³⁴But pasture fields of their cities shall not be sold, for that is their permanent possession.
