Leviticus 25:47-49

47“If an outsider or sojourner with you becomes rich, while your brother beside him has become poor and sells himself to the outsider dwelling among you or to a member of the outsider’s family,

48after he is sold he may be redeemed. One of his brothers may redeem him,

49or his uncle or his uncle’s son may redeem him, or anyone who is a close relative to him from his family may also redeem him. Or if he has grown rich, he may redeem himself.
