Leviticus 25:43-51

⁴³Thou shalt not rule over him with rigour; but shalt fear thy God.

⁴⁴Both thy bondmen, and thy bondmaids, which thou shalt have, shall be of the heathen 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 begat in your land: and they shall be your possession.

⁴⁶And ye shall take them as an inheritance for your children after you, to inherit them for a possession; they shall be your bondmen for ever: but over your brethren the children of Israel, ye shall not rule one over another with rigour.

⁴⁷And if a sojourner or stranger wax rich by thee, and thy brother that dwelleth by him wax poor, and sell himself unto the stranger or sojourner by thee, or to the stock of the stranger’s family:

⁴⁸after that he is sold he may be redeemed again; one of his brethren may redeem him:

⁴⁹either 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 able, he may redeem himself.

⁵⁰And he shall reckon with him that bought him from the year that he was sold to him unto the year of jubile: and the price of his sale shall be according unto the number of years, according to the time of a hired servant shall it be with him.

⁵¹If there be yet many years behind, according unto them he shall give again the price of his redemption out of the money that he was bought for.
