De Decalogo

The third commandment of the second table of five is not to steal. For he who keeps continually gaping after the property of others is the common enemy of the city, since, as far as his inclination goes, he would deprive all men of their property; and in respect of his power he actually does deprive some, because his covetousness is extended to the greatest imaginable length, and because his impotence, coming too late after it, is contracted into a small space, and can scarcely extend so as to overtake more than a few.

Therefore as many robbers as have the strength to do so plunder whole cities, paying no attention to the punishments with which they are threatened, because they appear to themselves to be superior to the laws. These are those men who are oligarchical in their natures, who have set their hearts on tyrannies and absolute power, who commit enormous thefts, concealing their robbery, as it is in reality, under the specious and imposing names of authority and supremacy.
