Leviticus 25:14-16

¹⁴And if thou sell aught unto thy neighbor, or buy aught of thy neighbor's hand, ye shall not overreach one the other;

¹⁵According to the number of years after the jubilee shalt thou buy of thy neighbor, according unto the number of harvest-years shall he sell unto thee;

¹⁶According to the multitude of years shalt thou increase the price thereof, and according to the fewness of years shalt thou diminish the price thereof; for a number of harvests doth he sell unto thee.
