Isaiah 37:33-36

“And this is what the LORD says about the king of Assyria: “‘His armies will not enter Jerusalem. They will not even shoot an arrow at it. They will not march outside its gates with their shields nor build banks of earth against its walls. The king will return to his own country by the same road on which he came. He will not enter this city,’ says the LORD. ‘For my own honor and for the sake of my servant David, I will defend this city and protect it.’” That night the angel of the LORD went out to the Assyrian camp and killed 185,000 Assyrian soldiers. When the surviving Assyrians woke up the next morning, they found corpses everywhere.
