Leviticus 25:25-29

25:25 “‘If your brother becomes impoverished and sells some of his property, his near redeemer is to come to you and redeem what his brother sold. 25:26 If a man has no redeemer, but he prospers and gains enough for its redemption, 25:27 he is to calculate the value of the years it was sold, refund the balance to the man to whom he had sold it, and return to his property. 25:28 If he has not prospered enough to refund a balance to him, then what he sold will belong to the one who bought it until the jubilee year, but it must revert in the jubilee and the original owner may return to his property.
