Leviticus 25:13-17

13“In this Year of Jubilee each of you will return to his property.

14“If you sell anything to your neighbor or buy from your neighbor, you are not to wrong one another.

15Corresponding to the number of years after the Jubilee you are to purchase land from your neighbor’s hand. He is to sell it to you based on the number of years of crops.

16In proportion to the extent of years you may increase its price, or decrease its price in proportion to the fewness of years, because he is selling a number of harvests to you.

17You are not to cheat one another, but fear your God, for I am Adonai your God.
