Leviticus 25:14-17

14And if thou sell ought unto thy neighbour, or buyest ought 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, and 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 according to the number of the years of the fruits doth he sell unto thee.

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