Isaiah 37:36–38

And the angel of the Lord went out and slew in the camp of the Assyrians a hundred and eighty-five thousand. And they arose in the morning, and behold they were all dead corpses. 37And Sennacherib the king of the Assyrians went out and departed, and returned, and dwelt in Ninive. 38And it came to pass, as he was worshipping in the temple of Nesroch his god, that Adramelech and Sarasar his sons slew him with the sword: and they fled into the land of Ararat, and Asarhaddon his son reigned in his stead.
