Leviticus 25:47-49

47"If a stranger or sojourner with you becomes rich, and your brother beside him becomes poor and sells himself to the stranger or sojourner with you or to a member of the stranger's clan,

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

49or his uncle or his cousin may redeem him, or a close relative from his clan may redeem him. Or if he grows rich he may redeem himself.
