2 Chronicles 32:20 MSG

[20] King Hezekiah, joined by the prophet Isaiah son of Amoz, responded by praying, calling up to heaven. God answered by sending an angel who wiped out everyone in the Assyrian camp, both warriors and officers. Sennacherib was forced to return home in disgrace, tail between his legs. When he went into the temple of his god, his own sons killed him.
