Isaiah 37:36-38

36Then the angel of Adonai went out and struck down 185,000 men in the Assyrian camp. When the men arose early in the morning, behold, they were all dead corpses.

37So King Sennacherib of Assyria withdrew, and returned home, and stayed in Nineveh.

38It also came to pass, as he was worshipping in the house of his god Nisroch, that his sons Adrammelech and Sarezer struck him down with the sword, and escaped into the land of Ararat. Then his son Esarhaddon became king in his place.
