Following a relentless chain of disasters and the sudden, miraculous blooming of Aaron's staff, a heavy terror of the Tabernacle and its holiness falls upon the Israelites. Their desperate plea to Moses is not another rebellion or complaint. Instead, it is a deep outpouring of sorrow, the sigh of a people paralyzed by fear and despair [ביאור יש״ר]. In their panic, some even suspect that God intentionally delayed the miracle of the staff to create an excuse to strike them down in various ways before Aaron's chosen status was finally proven [נחל קדומים].
Their panicked cry is threefold, and the primary approach among commentators is that this repetition specifically mirrors the three severe tragedies they recently endured. First, they speak of perishing, which recalls the two hundred and fifty men consumed by fire—a manifestation of God's strict justice [רבנו בחיי, פענח רזא] that instantly turned human flesh to ash [העמק דבר]. Alternatively, this first cry mourns those who died by the sword after trying to enter the land against God's command [ברכת אשר]. Second, they speak of being lost, pointing to the unnatural end of Korah and his followers who were swallowed alive by the earth and erased from the community [רבנו בחיי, העמק דבר, בכור שור]. Finally, their cry that they are entirely lost is a tragic reaction to the overwhelming number of people who died in the recent plague [רבנו בחיי, העמק דבר, בכור שור]. Claiming that they are all lost is a natural exaggeration born from the trauma of watching their numbers dwindle daily, leaving them feeling as though no one will survive [ביאור יש״ר, ברכת אשר], though some view this expression as a literal fear of total annihilation [נתינה לגר].
A different approach divides their cries more broadly, suggesting that perishing refers to natural deaths and plagues, while being lost refers to unnatural, divine punishments like burning and being swallowed [חזקוני, בכור שור]. Regardless of the exact breakdown, this overwhelming despair stems from a fundamental misunderstanding of the boundaries of holiness. At this stage, the Israelites have not yet been given clear distinctions between priests, Levites, and ordinary people regarding the work of the Tabernacle. They do not realize that danger only applies to outsiders performing the actual sacred service. Instead, they mistakenly assume that any approach to the Tabernacle, even just to stand guard, will end in certain death [רשב״ם, אבן עזרא, חזקוני].
Through this trauma, the people fully internalize the immense danger of approaching the holy, viewing it as a blazing fire that consumes anyone who steps too close. However, their panic is exaggerated. The law actually permits an ordinary Israelite to enter the Tabernacle for necessary tasks like building, maintenance, and removing impurities. The fatal consequences they fear are strictly reserved for those who intentionally step forward to perform the sacred service itself [רש״ר הירש].
