Both public and private sins are included in this prohibition. The eighth commandment condemns manstealing and slave dealing, and forbids wars of conquest. It condemns theft and robbery. It demands strict integrity in the minutest details of the affairs of life. It forbids overreaching in trade, and requires the payment of just debts or wages. It declares that every attempt to advantage oneself by the ignorance, weakness, or misfortune of another is registered as fraud in the books of heaven.
