ישעיהו, פרק ט׳, פסוק י״ח

God's intense anger unleashes a devastating chain reaction, beginning with a severe natural disaster and culminating in the total collapse of human society. Driven by His profound wrath [מצודת ציון, ביאור שטיינזלץ], a physical catastrophe strikes the land. The primary approach among commentators understands this ruin as a massive, scorching fire that consumes the earth [מצודת דוד, שד״ל, אברבנאל]. However, others view the disaster as a suffocating darkness and gloom, the result of heavy smoke blanketing the land [רד״ק, אבן עזרא]. This smoke is also described as being forcefully driven downward by storm winds, creating a rapid, destructive pillar of fire [רש״י, מלבי״ם]. Alternatively, the event is understood as the very earth shifting from its place [ביאור שטיינזלץ], sealing itself off [מלבי״ם], or suffering from a severe, scorching drought sent from the heavens to dry out the land [אברבנאל].

This overwhelming physical devastation directly triggers a social breakdown, where the society begins to consume itself from within. The people themselves become like fuel for a fire. Just as a burning log immediately ignites the wood resting next to it, harm spreads rapidly from one person to another [רד״ק, מצודת דוד, מלבי״ם]. The tragedy deepens because the suffering inflicted by outside forces is not enough; the people compound their troubles by turning on each other [רד״ק, מצודת דוד]. In the midst of such extreme disaster and ruin, all human compassion vanishes. Driven by sheer panic, each person cares only about saving himself [שד״ל]. Crushed by severe famine and drought, the people fall into deep despair, ultimately robbing their own neighbors simply to survive [אברבנאל].
