"The prophecies of judgment fall into three circles. The first of these contains the messages of the prophet delivered in the course of a public ministry during the reigns of Uzziah, Jotham, and Ahaz. The second contains the prophet's teaching in the course of a private ministry following upon the break of the prophet with Ahaz. The third contains the prophet's messages in a public ministry during the period of the threatened invasion by Assyria. "The messages of the first circle are largely concerning Judah and Jerusalem. Those of the second deal with the nations and the world. Those of the third have to do with the chosen and the world." —From Chapter 1
