Thematic Bible: Suburbs of their cities were inalienable for debt

And the cities of the Levites, the houses of the cities of their possession, redemption shall be always to the Levites. And whoever shall redeem from the Levites, and the selling of the house and the city of his possession went out in the jubilee; for the houses of the cities of the Levites, this their possession in the midst of the sons of IsraeL And the field of the area of their cities shall not be sold, for it is a possession to them forever.
