2 Kings 19:35

The angel of the Lord] cp. Exodus 12:23. In 2 Samuel 24:15 the pestilence that punished David's numbering of the people is attributed to an angel; and it is probable that it was a similar calamity that destroyed Sennacherib's army. It seems more likely that the disaster occurred in the low-lying ground on the Egyptian frontiers than in the neighbourhood of Jerusalem; and the Greek historian, Herodotus, who gives a fanciful account of an overthrow sustained by the Assyrians in a campaign against Egypt, places it near Pelusium. But wherever and however it happened, it was a signal confirmation of Isaiah's faith in the Lord and a striking vindication of his prescience.
