ישעיהו, פרק ט״ו, פסוק א׳

A sudden and devastating prophecy of doom descends upon the nation of Moab. Striking under the cover of darkness, a catastrophic event targets the kingdom's centers of power, leaving the entire nation paralyzed and completely helpless. This vision of disaster and defeat [רד״ק, מלבי״ם] is rooted in the historical conquest of Sennacherib, the King of Assyria, who is destined to destroy Moab and force its inhabitants into exile [רש״י, אברבנאל]. This severe punishment comes upon the Moabites partly because they refused to show mercy to the Israelites who sought refuge in their land while fleeing from those very same Assyrian forces [שד״ל].

The impending disaster focuses squarely on two major locations within Moab. The primary approach among commentators is that these were large, vital cities or capital districts that served as the foundation of the entire nation. A distinction is drawn between the two: one was an open, unwalled city situated on the country's border, while the other was a heavily fortified stronghold surrounded by defensive walls [מלבי״ם, שד״ל]. Despite their different defenses, both experience total ruin, robbery, and absolute loss [מצודת ציון].

The attack unfolds on a specific night destined for disaster [רד״ק, אבן עזרא, שד״ל, מלבי״ם]. This timing points to a sudden ambush that catches the residents fast asleep and entirely unprepared to defend themselves [רש״י, רד״ק, מצודת דוד, אברבנאל].

In the wake of this nighttime slaughter, the fate of the nation is understood in two complementary ways. On one level, the sheer destruction means the cities are entirely cut off and wiped out [רד״ק, אבן עזרא, אברבנאל, מצודת ציון]. The sudden collapse of the very strongholds the nation relied upon makes the surviving citizens feel as though their entire country has been erased from the earth [ביאור שטיינזלץ]. On another level, the aftermath is characterized by a profound, paralyzed silence. Because the invasion happens at night, the nation is caught sleeping and unaware of the approaching danger [רש״י, רד״ק]. The sudden ruin leaves Moab in total shock. The brave warriors and local heroes are struck dumb, their courage evaporating instantly. Rather than waking up to fight on the walls of their cities, they remain completely paralyzed by fear, reduced entirely to weeping and wailing [מלבי״ם, מצודת ציון, אברבנאל].
