Leviticus 25:29-30

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

³⁰If it isn’t redeemed within the space of a full year, then the house that is in the walled city shall be made sure in perpetuity to him who bought it, throughout his generations. It shall not be released in the Jubilee.
