“In addition to his use of the Babylonian Empire as a symbol of spiritual Babylon, Isaiah also sketches the demise of the great Assyrian Empire, which in the days of Hezekiah met crushing defeat upon the hills of Jerusalem at the hands of an angel of destruction (see Isaiah 37:33–38). Assyria also served as a type of the world. In like manner will all evil nations feel the hand of God’s judgments” (Old Testament Student Manual, 155).
