Leviticus 25:50-52 ▼

50 He then with his purchaser shall calculate from the year when he sold himself to him up to the year of jubilee; and the price of his sale shall correspond to the number of years. It is like the days of a hired man that he shall be with him.

51 If there are still many years, he shall return part of his purchase price in proportion to them for his own redemption;

52 and if few years remain until the year of jubilee, he shall so calculate with him. In proportion to his years he shall return the amount for his redemption.
