2 Chronicles 32:20-21

King Hezekiah and the prophet Isaiah son of Amoz cried out in prayer to heaven about this. And the LORD sent an angel, who annihilated all the fighting men and the commanders and officers in the camp of the Assyrian king. So he withdrew to his own land in disgrace. And when he went into the temple of his god, some of his sons, his own flesh and blood, cut him down with the sword.
