Leviticus 25:14-16

New Catholic Bible

¹⁴ If you sell some merchandise to your neighbor, or you buy something from your neighbor, you shall not take advantage of one another. ¹⁵ You shall buy from your neighbor based on the number of years since the Jubilee. He is to sell to you based on the number of years left for harvesting crops. ¹⁶ If the number of years left is greater, you shall increase the price paid, but if the number of years is smaller, then you shall decrease the price paid, for it is the number of harvests that he is selling you.
