and the LORD sent an angel who annihilated every mighty man of valor and every leader and commander in the camp of the king of Assyria. So he withdrew to his own land in disgrace. And when he entered the temple of his god, some of his own sons struck him down 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.
