Leviticus 25:32-34

32“ ‘The Levites always have the right to redeem their houses in the Levitical towns, which they possess. 33So the property of the Levites is redeemable—that is, a house sold in any town they hold—and is to be returned in the Jubilee, because the houses in the towns of the Levites are their property among the Israelites. 34But the pastureland belonging to their towns must not be sold; it is their permanent possession.
