Isaiah 14:29

Of him that smote thee: most understand this of Uzziah, who did them much mischief, 2 Chronicles 26:6; but he was dead thirty-two years before this time, and therefore their joy for his death was long since past. Others understand it of Ahaz; but he was so far from smiting them, that he was smitten by them, as was noted on Isaiah 14:28. It seems better to understand it more generally of the royal race or foregoing kings of Judah, who had been a terrible scourge to them, whose rod might be said to be broken, because that sceptre was come into the hands of slothful and degenerate princes, such as Ahaz was, who had been lately broken by the Philistines, and who probably was alive when this prophecy was delivered, because he here speaks of Hezekiah not as a present, but as a future king. It is said indeed that this burden was in the year that Ahaz died; but so it might be, though it was before his death. His fruit shall be a fiery flying serpent; from the root and race of David shall come Hezekiah, who, like a serpent, shall sting thee to death, as he did, 2 Kings 18:8.
