Leviticus 25:47-49

47And if a sojourner or a stranger shall become rich by thee, and thy brother that dwelleth by him shall become poor, and sell himself to the stranger or sojourner by thee, or to the stock of the stranger’s family:1 48After that he is sold he may be redeemed again; one of his brethren may redeem him: 49Either his uncle, or his uncle’s son, may redeem him, or any that is near of kin to him of his family may redeem him; or if he is able, he may redeem himself.
