Chapter 30 — Part III: The Decalogue — The Seventh Commandment
Section 14. Those who, in buying or selling, have recourse to fraud and lying, involve themselves in the same guilt. The Lord will avenge their trickery. Those who sell bad and adulterated goods as real and genuine, or who defraud the purchasers by weight, measure, number, or rule, are guilty of a species of theft still more criminal and unjust. It is written in Deuteronomy: Thou shalt not have divers weights in thy bag. Do not any unjust thing, says Leviticus, in judgment, in rule, in weight or in measure. Let the balance be just, and the weights equal, the bushel just, and the sextary equal. And elsewhere it is written: Divers weights are an abomination before the Lord; a deceitful balance is not good.
