Leviticus 25:30-32

New Life Version

³⁰ But if it is not bought back again for him within a whole year, then the house within the city walls belongs forever to the family of the one who bought it. It will not be returned to him in the Year of Jubilee. ³¹ But houses in towns that have no walls will be thought of as open fields. They may be let go, and will be returned in the Year of Jubilee. ³² The houses in the cities of the Levites may be returned to the Levites at any time.
