So now God heard Hezekiah's prayer, and he sends a message to Sennacherib saying,

Who is it you have ridiculed and blasphemed? Against whom have you raised your voice and lifted your eyes in pride? Against the Holy One of Israel! By your messengers you have ridiculed the Lord. And you have said, ‘With my many chariots I have ascended the heights of the mountains, the utmost heights of Lebanon. I have cut down its tallest cedars, the choicest of its junipers. I have reached its remotest heights, the finest of its forests. I have dug wells in foreign lands and drunk the water there. With the soles of my feet I have dried up all the streams of Egypt.’
“Have you not heard? Long ago I ordained it. In days of old I planned it; now I have brought it to pass, that you have turned fortified cities into piles of stone. Their people, drained of power, are dismayed and put to shame. They are like plants in the field, like tender green shoots, like grass sprouting on the roof, scorched before it grows up.
“But I know where you are and when you come and go and how you rage against me. Because you rage against me and because your insolence has reached my ears, I will put my hook in your nose and my bit in your mouth, and I will make you return by the way you came.

That whole speech is pretty humbling. I'm surprised Sennacherib still tried to attack.But even after the 185,000 died and he went home, he still worshiped other gods. It says:

One day, while he was worshiping in the temple of his god Nisrok, his sons Adrammelek and Sharezer killed him with the sword, and they escaped to the land of Ararat. And Esarhaddon his son succeeded him as king.

He's finally dead. But it's hard to believe his own sons killed him. He must have been a pretty horrible guy.
