2 Chronicles 32:20-22

But King Hezekiah and Isaiah the prophet, the son of Amoz, prayed about this and cried out to heaven. And the LORD sent an angel who destroyed every mighty warrior, commander and officer in the camp of the king of Assyria. So he returned in shame to his own land. And when he had entered the temple of his god, some of his own children killed him there with the sword. So the LORD saved Hezekiah and the inhabitants of Jerusalem from the hand of Sennacherib the king of Assyria and from the hand of all others, and guided them on every side.
