Leviticus 25:31-33

New King James Version

³¹ However the houses of villages which have no wall around them shall be counted as the fields of the country. They may be redeemed, and they shall be released in the Jubilee. ³² Nevertheless ^(A)the cities of the Levites, and the houses in the cities of their possession, the Levites may redeem at any time. ³³ And if a man purchases a house from the Levites, then the house that was sold in the city of his possession shall be released in the Jubilee; for the houses in the cities of the Levites are their possession among the children of Israel.
