Leviticus 25:25-30

25‘If one of your brethren becomes poor, and has sold some of his possession, and if his redeeming relative comes to redeem it, then he may redeem what his brother sold.

26Or if the man has no one to redeem it, but he himself becomes able to redeem it,

27then let him count the years since its sale, and restore the remainder to the man to whom he sold it, that he may return to his possession.

28But if he is not able to have it restored to himself, then what was sold shall remain in the hand of him who bought it until the Year of Jubilee; and in the Jubilee it shall be released, and he shall return to his possession.

29‘If a man sells a house in a walled city, then he may redeem it within a whole year after it is sold; within a full year he may redeem it.

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