Leviticus 25:49-51

King James Version

⁴⁹ Either 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.

⁵⁰ And 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 an hired servant shall it be with him.

⁵¹ If 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.
