He could not tell what really happened. Now the prophesy regarding his death comes true. While praying in his temple this man, Sennacherib, is killed by his two sons, so God's Wrath has fallen completely as prophesied on this man. The great Babylonian nation now comes and totally lays waste to this city to whom God had once shown great mercy. The events that were to come, has now happened.
History records the events and when compared to the events recorded in Nahum they go hand in hand.
This nation has God's Wrath upon them and He uses the Babylonian's to complete his judgement. You see, when God judges and His Wrath is upon a nation or a person, it is completed when there is no repentance . It starts with the Babylonian's coming to the gate and the final destruction of this once great city. Which leads us to the next point. So let us bring this to our own understanding, and to our own day.
