2 Chronicles 32:20-22

20King Hezekiah and the prophet Isaiah son of Amoz cried out in prayer to heaven about this. 21And 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. 22So the Lord saved Hezekiah and the people of Jerusalem from the hand of Sennacherib king of Assyria and from the hand of all others. He took care of them on every side.
