Leviticus

⁴³Thou shalt not rule over him with rigour; but shalt fear thy God. ⁴⁴And as for thy bondmen, and thy bondmaids, which thou shalt have; of the nations that are round about you, of them shall ye buy bondmen and bondmaids. ⁴⁵Moreover of the children of the strangers that do sojourn among you, of them shall ye buy, and of their families that are with you, which they have begotten in your land: and they shall be your possession. ⁴⁶And ye shall make them an inheritance for your children after you, to hold for a possession; of them shall ye take your bondmen for ever: but over your brethren the children of Israel ye shall not rule, one over another, with rigour. ⁴⁷And if a stranger or sojourner with thee be waxen rich, and thy brother be waxen poor beside him, and sell himself unto the stranger or sojourner with thee, or to the stock of the stranger's family: ⁴⁸after that he is sold he may be redeemed; one of his brethren may redeem him: ⁴⁹or his uncle, or his uncle's son, may redeem him, or any that is nigh of kin unto him of his family may redeem him; or if he be waxen rich, he may redeem himself.
