Leviticus 25:14-16

And if thou sell ought unto thy neighbour, or buyest {ought} of thy neighbour's hand, ye shall not oppress one another: According to the number of years after the jubile thou shalt buy of thy neighbour, {and} according unto the number of years of the fruits he shall sell unto thee: According to the multitude of years thou shalt increase the price thereof, and according to the fewness of years thou shalt diminish the price of it: for {according} to the number {of the years} of the fruits doth he sell unto thee.
