“Although the Watchtower asserts that the vision of Habakkuk pertains to the destruction of Christendom, which would mean that the Chaldean symbolizes the eighth king, they do not even attempt to explain the prophecy in that light. True, according to the vision of Habakkuk the work that Jehovah was working originally had to do with allowing the Babylonian armies to conquer Judah and Jerusalem. However, Nebuchadnezzar was also authorized by God to tyrannize and subjugate a large portion of the world of that day. So, if the destruction of Judah establishes a pattern for Christendom’s end, what is foreshadowed by the fact that the Chaldean likewise conquered all the other nations in that region of the earth?”
