Leviticus 25:32-34

32As for the cities of the Levites, the Levites have a permanent right of redemption for the houses in the cities which they possess.

33Therefore, what is [purchased] from the Levites may be redeemed [by a Levite], and the house that was sold in the city they possess reverts in the Year of Jubilee, for the houses in the Levite cities are their [ancestral] property among the Israelites.

34But the pasture lands of their cities may not be sold, for that is their permanent possession.
