Leviticus 25:30-32

New Revised Standard Version, Anglicised

³⁰ If it is not redeemed before a full year has elapsed, a house that is in a walled city shall pass in perpetuity to the purchaser, throughout the generations; it shall not be released in the jubilee. ³¹ But houses in villages that have no walls around them shall be classed as open country; they may be redeemed, and they shall be released in the jubilee. ³² As for the cities of the Levites, the Levites shall for ever have the right of redemption of the houses in the cities belonging to them.
