Leviticus 25:14-25:18
When you sell property to your neighbor, or buy any from your neighbor, you shall not wrong one another.In buying from your neighbor, you shall deduct only for the number of years since the jubilee; and in selling to you, he shall charge you only for the remaining crop years: the more such years, the higher the price you pay; the fewer such years, the lower the price; for what he is selling you is a number of harvests. Do not wrong one another, but fear your God; for I the Lord am your God.
You shall observe My laws and faithfully keep My rules, that you may live upon the land in security.
