Leviticus 25:47-52

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.

⁵²And if there remain but few years unto the year of the jubilee: then shall he reckon with him; according to his years shall he return the price of his redemption.
