Leviticus 25:44-49

⁴⁴“‘As for your male and your female slaves, whom you may have from the nations that are around you, from them you may buy male and female slaves.

⁴⁵Moreover, of the children of the aliens who live amongst you, of them you may buy, and of their families who are with you, which they have conceived in your land; and they will be your property.

⁴⁶You may make them an inheritance for your children after you, to hold for a possession. Of them you may take your slaves forever, but over your brothers the children of Israel you shall not rule, one over another, with harshness.

⁴⁷“‘If an alien or temporary resident with you becomes rich, and your brother beside him has grown poor, and sells himself to the stranger or foreigner living amongst you, or to a member of the stranger’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 any who is a close relative to him of his family may redeem him; or if he has grown rich, he may redeem himself.
