What causes a society to unravel? What offenses bring about a polity’s destruction? What types of behavior cause a society to forfeit its right to exist? In a sense, this has been the major theme of the book of Devarim: Moshe’s parting words to the nation abound with warnings against the sins that will result in exile from the land they are about to inherit. Indeed, Moshe’s exhortations and admonitions comprise such a large part of the text that it is difficult to “rank” them in terms of their destructiveness.
