Leviticus 25:48-52

48after he is sold he may be redeemed again. One of his brothers may redeem him;

49or his uncle or his uncle’s son may redeem him; or anyone who is near of kin to him in his family may redeem him; or if he is able he may redeem himself.

50Thus he shall reckon with him who bought him: The price of his release shall be according to the number of years, from the year that he was sold to him until the Year of Jubilee; it shall be according to the time of a hired servant for him.

51If there are still many years remaining, according to them he shall repay the price of his redemption from the money with which he was bought.

52And if there remain but a few years until the Year of Jubilee, then he shall reckon with him, and according to his years he shall repay him the price of his redemption.
