Thematic Bible: In villages, inalienable

But the houses of the villages which have no wall round about them shall be counted as the fields of the country: they may be redeemed, and they shall be released in the jubilee. Nevertheless the cities of the Levites, and the houses of the cities of their possession, may the Levites redeem at any time. And if a man purchases a house from the Levites, then the house that was sold, and the city of his possession, shall be released in the year of jubilee: for the houses of the cities of the Levites are their possession among the children of Israel.
