Leviticus 25:13-17

‘On this year of jubilee each of you shall return to his own property.

Furthermore, if you make a sale to your friend, or buy from your friend’s hand, you shall not wrong one another.

Corresponding to the number of years after the jubilee, you shall buy from your friend; he is to sell to you according to the number of years of crops.

In proportion to a greater number of years you shall increase its price, and in proportion to fewer years you shall decrease its price, because it is the number of crops that he is selling to you.

So you shall not wrong one another, but you shall fear your God; for I am the Lord your God.
