Leviticus 25:25-27

25If thy brother grow poor, and sell of his possession, then shall his redeemer, his nearest relation, come and redeem that which his brother sold.

26And if the man have no one having right of redemption, and his hand have acquired and found what sufficeth for its redemption,

27then shall he reckon the years since the sale thereof, and restore the overplus unto the man to whom he sold it; and so return unto his possession.
