2 Kings 19:19, 34-35

Now therefore, O LORD our God, I beseech thee, save thou us out of his hand, that all the kingdoms of the earth may know that thou art the LORD God, even thou only.

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 the LORD went out, and smote in the camp of the Assyrians an hundred fourscore and five thousand: and when they arose early in the morning, behold, they were all dead corpses.
