Leviticus 25:29-33

29“If a man sells a house in a walled city, then he may redeem it within a whole year after it has been sold. For a full year he has the right of redemption.

30But if it is not redeemed within the space of a full year, then the house that is in the walled city will belong permanently to the one who bought it throughout his generations. It will not be released in the Jubilee.

31But the houses of the villages that have no wall around them are to be considered as open country. They have redemption rights and are to be released in the Jubilee.

32“But as for the towns of the Levites, the Levites may have a permanent right of redemption for the houses in the towns of their possession.

33The Levites may redeem a house sold in the town of its possession. Also it shall be released in the Jubilee, for the houses of the Levitical towns are their possession among Bnei-Yisrael.
