2 Kings 19:35-37 King James Version (KJV)
35 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.
36 So Sennacherib king of Assyria departed, and went and returned, and dwelt at Nineveh.
37 And it came to pass, as he was worshipping in the house of Nisroch his god, that Adrammelech and Sharezer his sons smote him with the sword: and they escaped into the land of Armenia. And Esarhaddon his son reigned in his stead.
