Isaiah 37:36

The miraculous destruction of Sennacherib's host. It is certainly remarkable that none of Isaiah's prophecies delivered at the time predict this appalling disaster, the clearest anticipation of it being in ch. Isaiah 17:12-14, an oracle delivered some time before. At the same time some such occurrence is needed to account for Sennacherib's precipitate retreat before Tirhakah. A confirmation of the main fact is also found in the Egyptian tradition, according to which Sennacherib had already reached Pelusium in Egypt, when in a single night his army was rendered helpless by a plague of field-mice which gnawed the bows of the soldiers and the thongs of their shields (Herodotus, ii. 141). Since the mouse was among the Egyptians a symbol of pestilence we may infer that the basis of truth in the legend was a deadly epidemic in the Assyrian camp; and this is the form of calamity which is naturally suggested by the terms of the biblical narrative. The scene of the disaster is not indicated in the O.T. record, and there is no obstacle to the supposition that it took place, as in the Egyptian legend, in the plague-haunted marshes of Pelusium. The silence of Sennacherib about his misfortune is quite intelligible.

the angel of the Lord is associated with the plague in 2 Samuel 24:15-16.
