Leviticus 25:51-53

New King James Version

⁵¹ If 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. ⁵² And 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. ⁵³ He shall be with him as a yearly hired servant, and he shall not rule with rigor over him in your sight.
