Leviticus 25:15KJV

13In the year of this jubile ye shall return every man unto his possession.

14And if thou sell ought unto thy neighbour, or buyest of thy neighbour's hand, ye shall not oppress one another:

15According to the number of years after the jubile thou shalt buy of thy neighbour, according unto the number of years of the fruits he shall sell unto thee:

16According 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 to the number of the fruits doth he sell unto thee.

17Ye shall not therefore oppress one another; but thou shalt fear thy God: for I the LORD your God.
