God delivers a sharp rebuke to Sennacherib, the King of Assyria, systematically dismantling the monarch's pride over his vast military conquests. The primary approach among commentators is that the Assyrian king needed to understand a fundamental truth: he is nothing more than an instrument executing a divine plan that was set in motion long before his existence, leaving him with absolutely no reason to boast [רש״י, רלב״ג, רד״ק, אברבנאל].
Through the prophets, God challenges the king, asking if he has not heard that his sweeping victories were decreed by God in the distant past [רש״י, מצודת דוד, רלב״ג, אברבנאל]. In fact, Assyria's military success was conceived and planned from the very beginning of time, during the six days of creation [רש״י, רלב״ג, אברבנאל]. Only now is God bringing this ancient decree into reality. Sennacherib is merely the physical force through which God brings destruction upon the nations [רש״י, מצודת דוד, רד״ק, שטיינזלץ]. He is compared to an axe that cannot possibly claim greatness over the woodchopper who swings it, because every action and outcome ultimately originates from God [רד״ק, אברבנאל].
The fulfillment of this divine decree involves reducing powerful, fortified cities into desolate heaps of earth and rubble [מצודת ציון, רד״ק, ביאור שטיינזלץ]. Regarding the aftermath of this devastation, commentators offer different perspectives. One view suggests that the destruction is so absolute that wild flowers and plants eventually overtake the desolate mounds of dirt [רש״י, מצודת דוד, מצודת ציון]. Another perspective maintains that the aftermath is characterized solely by total ruin and devastation [רד״ק].
A completely different approach suggests that God is not referring to the destruction of foreign nations at the hands of Assyria, but rather to the fate of Jerusalem. According to this interpretation, God declares that He created and established Jerusalem in ancient times. He then asks a rhetorical question: is it even conceivable that He would now allow the city to be reduced to rubble and its inhabitants left defenseless? This reading emphasizes God's absolute commitment to protecting His city, making it clear that He will never permit the Assyrian king to destroy it [רד״ק, אברבנאל].
