Read Leviticus 25:33 Using Other Translations
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 jubile: for the houses of the cities of the Levites are their possession among the children of Israel.
And if one of the Levites exercises his right of redemption, then the house that was sold in a city they possess shall be released in the jubilee. For the houses in the cities of the Levites are their possession among the people of Israel.
And any property that is sold by the Levites—all houses within the Levitical towns—must be returned in the Year of Jubilee. After all, the houses in the towns reserved for the Levites are the only property they own in all Israel.
