2 Kings 19:32-36

32"Therefore thus says the Lord concerning the king of Assyria: He shall not come into this city or shoot an arrow there, or come before it with a shield or cast up a siege mound against it.

33By the way that he came, by the same he shall return, and he shall not come into this city, declares the Lord.

34For I will defend this city to save it, for my own sake and for the sake of my servant David."

35And that night the angel of the Lord went out and struck down 185,000 in the camp of the Assyrians. And when people arose early in the morning, behold, these were all dead bodies.

36Then Sennacherib king of Assyria departed and went home and lived at Nineveh.
