Following the devastating descriptions of ruin, the focus shifts entirely to the psychological and physical reality of the survivors driven into exile. These individuals are the ones who have managed to live through the preceding plagues and wars [אבן עזרא, ביאור יש״ר, שטיינזלץ], yet they stubbornly maintain their original flaws without turning back in repentance [אור החיים]. The ultimate purpose of their suffering in exile is to demonstrate that God's active supervision follows them beyond the borders of the land of Israel. This shatters their misguided assumption that exile frees them from the yoke of the Commandments, leaving them subject merely to the natural laws of foreign lands [העמק דבר].
While living under God's immediate presence in their homeland, the Israelites stood tall and fearless against massive armies. However, once distanced and seemingly abandoned, they are stripped of their vitality and lack the courage to face even the most minor threats [רד״צ הופמן, רש״ר הירש]. God brings an overwhelming terror, anxiety, and weakness into their hearts [רש״י, שטיינזלץ, אדרת אליהו]. The primary approach among commentators is that this condition represents a physical and emotional softening, where the blood retreats into the heart, leaving them entirely weak [רש״י, אבן עזרא, מלבי״ם, אילת השחר]. Others suggest it describes a literal breaking of the heart [רשב״ם, אבי עזר]. In a unique perspective, [בכור שור] views this intense fear as a positive, built-in defense mechanism. By remaining perpetually terrified, the exiles are kept from provoking the surrounding nations, ensuring their survival. Ultimately, the continuous nature of these hardships serves as proof that despite enduring endless suffering, the nation as a whole will never be completely wiped out [אור החיים].
In this state of constant, paralyzing anxiety, the exiles feel so profoundly vulnerable that the lightest, most natural sound terrifies them. They will run in a panic, convinced an invading army is upon them [אדרת אליהו], even when the local populations show them no overt hostility [נתינה לגר]. Commentators note the mechanics of this sound, explaining that a single leaf moving in the wind is completely silent. The terrifying noise is only produced when the wind forces one leaf to violently strike another [רש״י, שד״ל, מזרחי, שפתי חכמים, מלבי״ם, ביאור יש״ר].
This imagery of colliding leaves carries profound social and spiritual implications. [כלי יקר] views it as a reflection of the deep disunity and destructive gossip plaguing the exiled Israelites. Just as the wind forces one leaf to strike the next, the Israelites are battered by the nations. Yet, instead of uniting for comfort, they turn on each other, tripping their peers and striking them with cruel words. The malicious joy and gossip they spread become the very noise that torments them. On a spiritual level, [פרדס יוסף] cites the Baal Shem Tov, who interprets the leaf as a page of Torah study. When a person studies purely to provoke or mock others, the very page they read becomes a force that relentlessly pursues them.
Consumed by this manufactured dread, the survivors will sprint away as if armed soldiers are actively hunting them down, even though the landscape is completely empty of enemies [רש״י, מזרחי, לבוש האורה, גור אריה]. Blinded by panic, they will stumble over one another, entirely stripped of any ability to cooperate or act as a unified group [רלב״ג, רש״ר הירש]. Ultimately, they will collapse to the ground. There is no external enemy striking them down; it is their own exhaustion, weakness, and sheer terror that cause their fall [מלבי״ם, אדרת אליהו, שטיינזלץ]. [חזקוני] notes that this sequence of distinct afflictions, including the softened heart, the terrifying sound of the leaf, the desperate flight, and the final collapse, serves to complete the overarching punishment for the Jubilee years that the nation previously ignored.
