Leviticus 25:50-52

Revised Standard Version

⁵⁰ He shall reckon with him who bought him from the year when he sold himself to him until the year of jubilee, and the price of his release shall be according to the number of years; the time he was with his owner shall be rated as the time of a hired servant. ⁵¹ If there are still many years, according to them he shall refund out of the price paid for him the price for his redemption. ⁵² If there remain but a few years until the year of jubilee, he shall make a reckoning with him; according to the years of service due from him he shall refund the money for his redemption.
