Thematic Bible: In villages, inalienable

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. As for the cities of the Levites, the houses in the cities which they possess, the Levites must have a perpetual right of redemption. 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.
