Isaiah 37:36-38

    "Then the Angel of the LORD went out, and killed in the camp of the Assyrians one hundred and eighty-five thousand; and when people arose early in the morning, there were corpses-all dead.  So Sennacherib king of Assyria departed and went away, returned home, and remained in Ninevah.  Now it came to pass, as he was worshiping in the house of Nisroch his god, that his sons Adrammelech and Shareser struck him down with the sword; and they escaped into the land of Ararat.  Then Esarhaddon his son reigned in his place."
