Leviticus 25:16-18

New Revised Standard Version, Anglicised Catholic Edition

¹⁶ If the years are more, you shall increase the price, and if the years are fewer, you shall diminish the price; for it is a certain number of harvests that are being sold to you. ¹⁷ You shall not cheat one another, but you shall fear your God; for I am the Lord your God.

¹⁸ You shall observe my statutes and faithfully keep my ordinances, so that you may live on the land securely.
