Leviticus 25:15-17

New Revised Standard Version, Anglicised Catholic Edition

¹⁵ When you buy from your neighbour, you shall pay only for the number of years since the jubilee; the seller shall charge you only for the remaining crop-years. 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.
