Leviticus 25:14-16

¹⁴'And when thou sellest anything to thy fellow, or buyest from the hand of thy fellow, ye do not oppress one another;

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;
