Leviticus 25:13-17

13In the year of this jubilee ye shall return every man to his possession. 14And if thou shalt sell any to thy neighbour, or buy any thing from thy neighbour’s hand, ye shall not oppress one another: 15According to the number of years after the jubilee thou shalt buy of thy neighbour, and according to the number of years of the fruits he shall sell to thee: 16According to the multitude of years thou shalt increase the price of it, 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 to thee. 17Ye shall not therefore oppress one another; but thou shalt fear thy God: for I am the LORD your God.
