במדבר, פרק כ״א, פסוק ט׳

The healing process following the plague of venomous snakes in the desert demands more than a simple medical remedy. It requires the Israelites to engage in an active, internal struggle, facing the very source of their pain by looking up at a physical representation of it raised high above the camp. God originally commanded Moses to craft a fiery serpent, yet Moses ultimately created a standard snake made of copper. This shift reveals a deeper layer of the narrative, rooted in the dual nature of the Israelites' rebellion. They had spoken against both God and Moses, and as a result, two different types of creatures attacked them: ordinary snakes to avenge God's honor, and fiery serpents to avenge Moses's honor. When the people sought forgiveness, God instructed Moses to make a fiery serpent. By doing so, God essentially forgave the offense against His own honor, leaving Moses to address the slight against himself. However, Moses, acting with profound humility, forgave the insult to his own honor and instead crafted a snake to atone for the people's offense against God [הטור הארוך, ריב״א, ברטנורא, משכיל לדוד].

The decision to cast the figure in copper carries multiple layers of meaning. The primary approach among commentators is that the linguistic similarity between the name of the material and the object itself highlights a profound, essential connection between the two. Furthermore, the fiery serpent that attacked the camp was a specific type of venomous snake characterized by red eyes and a copper-colored neck, making copper the most visually accurate material to use [רמב״ן, רבינו בחיי, מלבי״ם]. The concept of a fiery serpent also evokes something burning and refined in fire, perfectly matching the bright, sparkling nature of polished copper [תורה תמימה, אם למקרא, דברי דוד]. This brilliant gleam served a practical purpose as well, allowing every individual, even those at the far edges of the massive camp, to clearly see the figure [חזקוני]. On a symbolic level, Moses deliberately chose simple copper over prestigious gold. This served as a stark reminder of their sin, as they had behaved with the deceit of the primordial serpent, while also ensuring the people would not be tempted to worship the object as an idol [ספורנו, שטיינזלץ].

Moses placed the copper snake upon a high pole. This elevated position functioned much like a father who hangs a disciplinary strap in plain sight, ensuring his children will constantly see it and remember the lesson [קיצור בעל הטורים]. The actual healing mechanism—where a bitten person simply looked at the copper snake and survived—is widely understood as a miracle within a miracle. According to the laws of nature and medicine, a person bitten by a venomous creature experiences immense anxiety. Merely seeing the animal that attacked them, or even being reminded of it, can trigger a panic severe enough to worsen their condition or lead to death. The natural expectation would be to remove all traces of snakes from the victims' sight. Yet, God deliberately chose to heal the people using the exact image of their harm, proving undeniably that their recovery depended entirely on divine providence rather than the laws of nature [רמב״ן, רבינו בחיי, הטור הארוך, מלבי״ם, ביאור יש״ר, חזקוני, פענח רזא, הדר זקנים].

The physical threat was not entirely removed; the live snakes continued to roam the camp and bite the people, leaving the choice to seek healing entirely up to each individual [ביאור יש״ר]. The act of looking at the elevated copper snake was not meant to be a superficial glance, but rather a moment of deep, intellectual, and internal contemplation [מלבי״ם, נתינה לגר]. As the bitten Israelites cast their eyes upward, they were simultaneously lifting their hearts in submission to God and subduing their own destructive impulses. Through this profound visual encounter, they internalized a critical truth: it is not the snake that brings death, nor the copper figure that brings life. Rather, it is sin that kills, and it is God alone who heals [רא״ש, חזקוני].
