Wherefore it shall come to pass— We have in this verse the punishment which God decreed for the king of Assyria, after he had performed all that work for which God raised him up. Bishop Newton observes, that this verse intimates that the Assyrians should be severely punished for their pride, ambition, tyranny, and cruelty, after they had served the purposes of divine providence. There was no prospect of such an event while the Assyrians were in the midst of their successes and triumphs; but still the word of the prophet prevailed; and it was not long after these calamities brought upon the Jews, that the Assyrian empire, properly so called, was overthrown, and Nineveh destroyed. Instead of I will punish the fruit, &c. Bishop Lowth reads, I will punish the effect, &c.
