במדבר, פרק כ״א, פסוק ד׳

Moments before the end of their forty years of wandering, standing on the threshold of the Promised Land, the Israelites experience a profound crisis that forces them to retreat. A breaking point of physical and mental exhaustion shatters their hope for a breakthrough, replacing it with bitter despair. The primary approach among commentators is that their journey south toward the Gulf of Aqaba was entirely unplanned. It was forced upon the nation after the kings of Edom and Moab refused to allow them passage through their territories [חזקוני, שטיינזלץ, רבנו בחיי, אבן עזרא]. However, beyond a mere geographic detour, this change in direction triggered a traumatic retreat. Following Aaron's death at Mount Hor, the Clouds of Glory that had shielded the camp departed. This sudden vulnerability invited an attack by the Canaanite king of Arad, causing the Israelites to flee backward in panic for a distance of seven travel stages. The retreat only ended when the tribe of Levi fought the fleeing masses, forcing them to halt at Moserah. There, broken and devastated, the people mourned Aaron, whose passing had set this chain of disasters into motion [רש״י, מזרחי, גור אריה].

The emotional toll of these events manifested as a severe shortness of spirit, a state of impatience where the soul becomes too narrow to contain its sorrow, stripping a person of the ability to wait patiently for their goal [שד״ל, רש״ר הירש, ברכת אשר]. Commentators point to a combination of psychological and physical factors that caused this breakdown. Psychologically, the sheer agony of retreating was overwhelming. Being so close to their final destination only to be pushed away onto a long, roundabout path was far more crushing than embarking on a lengthy journey from the start [העמק דבר]. Furthermore, returning to the route near the Red Sea reminded the people of the path they had walked after the sin of the spies, sparking a deep anxiety that they were doomed to wander the desert forever [רש״י, פני דוד]. Physically, the loss of the Clouds of Glory drastically altered the reality of their travel. While the clouds had previously carried them with ease, flattened mountains, and shielded them from the elements, the Israelites were now forced to walk on foot, exposed to the scorching sun by day and the freezing cold by night [שפתי כהן, חזקוני, מלבי״ם, אלשיך].

Some draw a distinction between the shortness of spirit the Israelites experienced during their enslavement in Egypt and their current despair. In Egypt, brutal labor clouded their minds and prevented clear thought. Here, however, their minds were clear. They had the capacity to reflect on the miracles that had accompanied them for forty years and to place their trust in God. Their choice to surrender to despair rather than quiet their souls is what ultimately led to their punishment [ביאור יש״ר]. This deep frustration quickly erupted into complaints about their food and water. Their fear of the future was only amplified by the sight of passing merchants carrying fresh fruits from the land of Israel. Encountering natural, tangible produce caused them to reject the spiritual manna, which they felt lacked physical substance for the eye and palate, and failed to provide them with real strength. Paralyzed by anxiety, they feared that just as Aaron and Miriam had died, Moses would soon pass away as well. They believed that once he was gone, the miraculous provisions of manna and water would cease entirely, leaving them to starve in the wilderness [דעת זקנים, צרור המור, בכור שור, פני דוד, אלשיך].
