Leviticus 25:15-17 New American Bible (Revised Edition) (NABRE)
15 On the basis of the number of years since the last jubilee you shall purchase the land from your neighbor; and so also, on the basis of the number of years of harvest, that person shall sell it to you. 16 When the years are many, the price shall be so much the more; when the years are few, the price shall be so much the less. For it is really the number of harvests that the person sells you. 17 Do not deal unfairly with one another, then; but stand in fear of your God. I, the Lord, am your God.
