Leviticus 25:15-17

¹⁵by the number of years after the jubilee thou dost buy from thy fellow; by the number of the years of increase he doth sell to thee;

¹⁶according to the multitude of the years thou dost multiply its price, and according to the fewness of the years thou dost diminish its price; for a number of increases he is selling to thee;

¹⁷and ye do not oppress one another, and thou hast been afraid of thy God; for I am Jehovah your God.
