Leviticus 25:14-17

“When you make an agreement with your neighbor to buy or sell property, you must not take advantage of each other. When you buy land from your neighbor, the price you pay must be based on the number of years since the last jubilee. The seller must set the price by taking into account the number of years remaining until the next Year of Jubilee. The more years until the next jubilee, the higher the price; the fewer years, the lower the price. After all, the person selling the land is actually selling you a certain number of harvests. Show your fear of God by not taking advantage of each other. I am the LORD your God.
