Chapter 30 — Part III: The Decalogue — The Seventh Commandment

Section 19. Various Forms Of Robbery — The pastor, therefore, should next come to treat of robbery, which is the second general division of these crimes. First, he should admonish the Christian people to bear in mind the teaching of the Apostle: They that will become rich fall into temptation, and the snare of the devil; and never to forget the rule: All things whatsoever you will that men do to you, do you also to them; and always to bear in mind the words of Tobias: See thou never do to another what thou wouldst hate to have done to thee by another.
