The document provides commentary on Isaiah 19, which contains a prophecy against Egypt. It begins by explaining the meaning and origins of the name "Egypt" and discussing how God is depicted as riding upon a cloud when coming to inflict punishment. It then analyzes each verse and explains what judgments God will bring against Egypt, including causing their idols to tremble and the people's courage to fail. The commentators discuss how this prophecy refers to divisions and civil wars in Egypt as well as the Assyrian invasion during the time of Isaiah.
