Leviticus 25:43-51

⁴³Thou shalt not rule over him with rigor; but thou shalt have fear of thy God.

⁴⁴But thy bond-man, and thy bond-woman that shall remain thine, shall be of the nations that are round about you; of them may ye buy bond-man and bond-woman.

⁴⁵And also of the children of the strangers that sojourn with you, of them may ye buy, and of their families that are with you, which they have begotten in your land; and they shall remain to you as a possession.

⁴⁶And ye may transfer them as an inheritance for your children after you, to inherit them for a possession; you may hold them to service for ever; but over your brethren the children of Israel, one over the other, ye shall not rule with rigor.

⁴⁷And if a stranger or sojourner wax rich near thee, and thy brother become poor near him, and he sell himself unto the sojourning stranger near thee, or to a descendant of a stranger's family:

⁴⁸After he hath sold himself shall he have the right of redemption; one of his brethren may redeem him.

⁴⁹Either his uncle, or his uncle's son, may redeem him, or any that is near of kin unto him of his family may redeem him; or if he obtain the means, he may redeem himself.

⁵⁰And he shall reckon with him that bought him from the year that he sold himself to him unto the year of the jubilee: and the price of his sale shall be according to the number of years, as the time of a hired laborer shall he have been with him.

⁵¹If there be yet many years, according to them shall he return the price of his redemption out of his purchase-money.
