2 Chronicles 32:20-21

32:20 King Hezekiah and the prophet Isaiah son of Amoz prayed about this and cried out to heaven. 32:21 The Lord sent a messenger and he wiped out all the soldiers, princes, and officers in the army of the king of Assyria. So Sennacherib returned home humiliated. When he entered the temple of his god, some of his own sons struck him down with the sword.
