Leviticus 25:29-34
Release of Houses
25:29 “‘If a man sells a residential house in a walled city, its right of redemption must extend until one full year from its sale; its right of redemption must extend to a full calendar year.
25:30 If it is not redeemed before the full calendar year is ended, the house in the walled city will belong without reclaim to the one who bought it throughout his generations; it will not revert in the jubilee.
25:31 The houses of villages, however, which have no wall surrounding them must be considered as the field of the land; they will have the right of redemption and must revert in the jubilee.
25:32 As for the cities of the Levites, the houses in the cities which they possess, the Levites must have a perpetual right of redemption.
25:33 Whatever someone among the Levites might redeem – the sale of a house which is his property in a city – must revert in the jubilee, because the houses of the cities of the Levites are their property in the midst of the Israelites.
25:34 Moreover, the open field areas of their cities must not be sold, because that is their perpetual possession.
