Leviticus 25:14-17

“If you sell or buy property from one of your countrymen, don’t cheat him. Calculate the purchase price on the basis of the number of years since the Jubilee. He is obliged to set the sale price on the basis of the number of harvests remaining until the next Jubilee. The more years left, the more money; you can raise the price. But the fewer years left, the less money; decrease the price. What you are buying and selling in fact is the number of crops you’re going to harvest. Don’t cheat each other. Fear your God. I am GOD, your God.
