And the LORD sent an angel, who cut off all the mighty warriors and commanders and officers in the camp of the king of Assyria. So he returned with shame of face to his own land. And when he came into the house of his god, some of his own sons struck him down there with the sword.
Sennacherib's malice cuts two ways at once: he undermines Hezekiah's authority by whispering to the people that their king will starve them, and he blasphemes God Himself, comparing the Maker of heaven and earth to the dead idols of conquered nations. Mark how a man's pride in his own conquests becomes the fuel for his impiety.
