Leviticus

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. ⁵⁰And he shall reckon with him that bought him from the year that he sold himself 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 an hired servant shall he be with him. ⁵¹If there be yet many years, according unto them he shall give back the price of his redemption out of the money that he was bought for. ⁵²And if there remain but few years unto the year of jubile, then he shall reckon with him; according unto his years shall he give back the price of his redemption. ⁵³As a servant hired year by year shall he be with him: he shall not rule with rigour over him in thy sight.
