2 Kings 19:32-36

Therefore thus saith Jehovah concerning the king of Assyria, He shall not come unto this city, nor shoot an arrow there, neither shall he come before it with shield, nor cast up a mound against it. By the way that he came, by the same shall he return, and he shall not come unto this city, saith Jehovah. For I will defend this city to save it, for mine own sake, and for my servant David’s sake. And it came to pass that night, that the angel of Jehovah went forth, and smote in the camp of the Assyrians a hundred fourscore and five thousand: and when men arose early in the morning, behold, these were all dead bodies. So Sennacherib king of Assyria departed, and went and returned, and dwelt at Nineveh.
