ישעיהו, פרק ב׳, פסוק י״ט

The impending day of judgment brings a terrifying reality to earlier prophetic warnings. What was previously a mere call to seek shelter from God now unfolds as an inescapable event [מלבי״ם, ביאור שטיינזלץ]. As God inspires overwhelming fear, the inhabitants of the earth—particularly the wicked and those who worship idols—will run for their lives. Driven by panic, they will operate under the false hope that they can somehow escape His reach and find a safe haven [רש״י, רד״ק, מצודת דוד].

In their desperation, these fleeing masses will look for shelter deep underground. While some commentators view the various underground spaces they seek as simple, synonymous caves [רש״י, מצודת ציון], others draw a sharp distinction between the types of hiding places. According to this perspective, some will flee to natural caves formed in solid rock, seeking a strong physical barrier for protection. Others, however, will resort to digging artificial holes in soft dirt. These dug-out spaces offer no true physical defense; they are merely a desperate attempt to disappear from sight [מלבי״ם].

This worldwide panic occurs exactly on the day of judgment, the moment God takes active measures [רש״י]. The primary approach among commentators is that His purpose at this time is to completely shatter and crush the wicked of the earth [רש״י, רד״ק, מצודת ציון], an idea rooted in the concept of breaking and destroying [שד״ל]. In contrast, another perspective suggests that this moment is about establishing absolute authority, as God arises to assume full rule and dominion over the earth [ביאור שטיינזלץ].
