Chapter 32 — Part III: The Decalogue — The Ninth and Tenth Commandments
Section 19. When, therefore, the Law says: Thou shalt not covet, it means that we are not to desire those things which belong to others. A thirst for what belongs to others is intense and insatiable; for it is written: A covetous man shall not be satisfied with money; and of such a one Isaias says: Woe to you that join house to house, and lay field to field.
