Leviticus 25:25-27

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.
