At last in a single night the deliverance miraculously came. It is implied by the scattered accounts of those days of salvation, that an Assyrian corps continued to sit before Jerusalem even after the Rabshakeh had returned to the headquarters of Sennacherib. The thirty-third of Isaiah, as well as those Psalms which celebrate the Assyrian's disappearance from Judah, describe it as having taken place from under the walls of Jerusalem and the astonished eyes of her guardians. It was not, however, upon this force--perhaps little more than a brigade of observation (xxxiii. 18)--that the calamity fell which drove Sennacherib so suddenly from Syria. _And there went forth_ (_that night_, adds the book of Kings) _the angel of Jehovah; and he smote in the camp of Assyria one hundred and eighty-five thousand; and when the camp arose in the morning, behold all of them were corpses, dead men. And Sennacherib, King of Assyria, broke up, and returned and dwelt in Nineveh._ Had this pestilence dispersed the camp that lay before Jerusalem, and left beneath the walls so considerable a number of corpses, the exclamations of surprise at the sudden disappearance of Assyria, which occur in Isa. xxxiii. and in Psalms xlviii. and lxxvi., could hardly have failed to betray the fact. But these simply speak of vague _trouble_ coming _upon them that were assembled about Zion_, and of their swift decampment. The trouble was the news of the calamity, whose victims were the main body of the Assyrian army, who had been making for the borders of Egypt, but were now scattered northwards like chaff.
