A tragic irony often unfolds when a nation seeks safety in the arms of foreign empires, only to discover that its chosen protectors have become its cruelest conquerors. A piercing rhetorical question is posed to the Israelites, highlighting the disaster approaching them. They are asked what justification, excuse, or apology they will possibly be able to offer when a sudden reckoning arrives [מצודת דוד, מלבי״ם, ביאור שטיינזלץ].
Commentators differ on the exact nature of this coming judgment. Some explain that God Himself will hold the people accountable and punish them for their sins [רש״י, רד״ק]. Another approach suggests that the reckoning will come directly from the Babylonian or Assyrian armies, who will invade the land and exile its inhabitants [רד״ק, מצודת דוד]. In this view, the king of Babylon will arrive as a sovereign demanding answers for the nation's rebellion against him, much like an owner reclaiming his flock [מלבי״ם, ביאור שטיינזלץ].
The root cause of this impending catastrophe lies in the actions of the Israelites themselves. Through their own choices, they accustomed foreign superpowers to rule over them. Historically, this submission took several forms. Spiritually, they sent messengers to the Chaldeans to import foreign idols and adopt their worship [רש״י]. Economically, King Hezekiah once displayed all of his royal treasures to Babylonian envoys. This fateful decision awakened their greed, inciting them to repeatedly wage war against Israel in order to plunder its wealth [רש״י, מצודת דוד]. Politically, King Ahaz had previously appealed to the king of Assyria for military aid against his enemies, declaring himself a servant and a son to the foreign ruler. By swearing such allegiance and subordinating himself, he drew distant empires close and effectively crowned them as leaders over his own people [רד״ק, מלבי״ם].
The ultimate consequence of these actions is severe agony. When the enemy finally arrives to assert total control and punish the rebellion, the Israelites will be overwhelmed by intense suffering, terror, and helplessness. They will find themselves trapped in gripping pain, suffering exactly like a woman in the throes of childbirth [מצודת דוד, רד״ק, מלבי״ם].
