Leviticus 25:32-33
Leviticus 25: 32 to 33
32 Notwithstanding the cities of the Levites, and the houses of the cities of their possession, may the Levites redeem at any time.
33 And if a man purchase of the Levites, then the house that was sold, and the city of his possession, shall go out in the year of jubilee: for the houses of the cities of the Levites are their possession among the children of Israel.
