Leviticus 25:47-49

The Voice

⁴⁷ If a foreigner or outsider living among you becomes rich enough to buy a slave, and one of your fellow citizens has become poor enough he has to sell himself as a slave to him or to his extended family, ^48-49 then your fellow citizen has the right to be redeemed. One of his brothers, his uncle, his cousin, or any more distant relative may buy him back. If he makes enough money, he can purchase his own freedom.
