Leviticus 25:30-32

King James Version

³⁰ And if it be not redeemed within the space of a full year, then the house that is in the walled city shall be established for ever to him that bought it throughout his generations: it shall not go out in the jubile.

³¹ But the houses of the villages which have no wall round about them shall be counted as the fields of the country: they may be redeemed, and they shall go out in the jubile.

³² Notwithstanding the cities of the Levites, and the houses of the cities of their possession, may the Levites redeem at any time.
