Leviticus 25:47-49

‘Now if a sojourner or stranger close to you becomes rich, and one of your brethren who dwells by him becomes poor, and sells himself to the stranger or sojourner close to you, or to a member of the stranger’s family, after he is sold he may be redeemed again. One of his brothers may redeem him; or his uncle or his uncle’s son may redeem him; or anyone who is near of kin to him in his family may redeem him; or if he is able he may redeem himself.
