במדבר, פרק י״ז, פסוק י״א

In a moment of terrifying crisis, a deadly plague begins to sweep through the Israelite camp following a rebellion. Faced with this disaster, Moses and Aaron immediately step forward to save the very people who had just turned against them. Although God had instructed the two leaders to step away so He could destroy the congregation, they ignore their personal honor. Driven by a deep love for the people, they rush into danger to stop the devastation [ביאור יש״ר, בעלי ברית אברם].

The primary approach among commentators is that the choice of incense as the tool for salvation was intended to convey a profound educational message. Because two hundred and fifty men had recently died while offering incense, the Israelites had come to view it as a deadly poison. Moses wanted to prove that incense itself does not kill. On the contrary, when offered by the chosen and worthy priest, it brings life and halts disease [אור החיים, רשב״ם, בכור שור, חזקוני]. Furthermore, Moses moved with absolute certainty because of a secret revealed to him by the Angel of Death when he ascended to heaven to receive the Torah. He knew that incense possessed the unique ability to appease divine judgment and stop plagues [רש״י, רקנאטי, משכיל לדוד].

This rescue mission required strict procedures and a willingness to bypass standard laws. Moses instructed Aaron to use a specific, familiar fire pan, likely the one he had used the day before [ביאור יש״ר, אבן עזרא]. He was directed to take holy fire from the outer altar rather than ordinary fire. This careful instruction prevented Aaron from panicking in the emergency and mistakenly bringing unauthorized fire, an error that had previously caused the deaths of Nadab and Abihu [רלב״ג, ביאור יש״ר, חזקוני, שפתי כהן]. Aaron then added the standard daily incense [ביאור יש״ר]. Normally, burning incense outside the Tent of Meeting is a severe violation, but Moses understood that saving a life overrides all other rules. To minimize the violation, Moses told Aaron to place the incense on only one side of the coals so it would ignite naturally as he ran, rather than being actively burned by his hands right away [העמק דבר].

Aaron was told to move with extreme speed. Running ensured that the Israelites would recognize the salvation as coming directly from God, preventing them from believing that Aaron's specific fire pan held magical powers [אבן עזרא, ביאור יש״ר, שפתי כהן]. Moses initially directed Aaron toward the elders gathered near the Tent of Meeting, assuming the plague would strike them first. In reality, the disease erupted among the masses further back, forcing Aaron to rush directly into the chaotic crowd [מלבי״ם]. Moses had sensed the outbreak prophetically, even before he could confirm that people were dying [שד״ל]. He recognized the emergence of a specific destroying angel, a force of strict divine justice that he remembered from the sin of the Golden Calf [רבנו בחיי, שפתי כהן, רקנאטי, הכתב והקבלה]. This destroyer was advancing systematically from the edge of the camp inward, cutting down lives just as a farmer harvests grain in a field [רבנו בחיי, בעלי ברית אברם].

Ultimately, the smoke of the incense formed a protective physical and spiritual barrier against the plague [חזקוני]. By specifically appointing Aaron to perform this act of atonement, Moses sent a powerful final message. He demonstrated to the Israelites that despite their recent attempts to undermine Aaron's priesthood, Aaron held no desire for their destruction and was willing to risk everything to grant them life [ביאור יש״ר].
