And it all came to pass, for that night the Angel of the Lord went forth and slew 185,000 in the camp of the Assyrians; and when [the living] arose early in the morning, behold, all these were dead bodies.
He let loose upon them the fierceness of His anger, His wrath and indignation and distress, by sending [a mission of] angels of calamity and woe among them.
And at once an angel of the Lord smote him and cut him down, because he did not give God the glory (the preeminence and kingly majesty that belong to Him as the supreme Ruler); and he was eaten by worms and died.
