Leviticus 25:25-27
25ΒΆ If thy brother be waxen poor, and hath sold away some of his possession, and if any of his kin come to redeem it, then shall he redeem that which his brother sold. 26And if the man have none to redeem it, and himself be able to redeem it; 27Then let him count the years of the sale thereof, and restore the overplus unto the man to whom he sold it; that he may return unto his possession.
