Thematic Bible: In villages, inalienable

But 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. Nevertheless the cities of the Levites, the houses of the cities of their possession, the Levites may redeem at any time. And if a man purchases from the Levites, then the house that was sold, and 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 sons of Israel.
