Leviticus 25:31

The Message

^29-31 “If a man sells a house in a walled city, he retains the right to buy it back for a full year after the sale. At any time during that year he can redeem it. But if it is not redeemed before the full year has passed, it becomes the permanent possession of the buyer and his descendants. It is not returned in the Jubilee. However, houses in unwalled villages are treated the same as fields. They can be redeemed and have to be returned at the Jubilee.
