Leviticus 25:32

³⁰And if it be not ransomed until there be completed of its time a full year, the house which is in the walled city shall be surely confirmed to him that bought it, throughout his generations; and it shall not go out in the release.

³¹But the houses in the villages which have not a wall round about them, shall be reckoned as the fields of the country: they shall always be redeemable, and they shall go out in the release.

— Leviticus 25:32 —

³³And if anyone shall redeem a house of the Levites, then shall their sale of the houses of their possession go out in the release; because the houses of the cities of the Levites are their possession in the midst of the children of Israel.

³⁴And the lands set apart for their cities shall not be sold, because this is their perpetual possession.
