ויקרא, פרק י׳, פסוק ט״ז

On the eighth day of the Tabernacle's dedication, which coincided with the first of Nissan, tragedy struck with the sudden death of Aaron's sons, Nadab and Abihu. Amidst this heavy mourning, a practical and legal tension arose regarding the consumption of the day's sacrifices. Moses instructed Aaron and his surviving sons to eat the sacrificial portions as usual, despite their status as pre-burial mourners, to ensure the joy of the dedication was not disrupted. However, an investigation into the day's proceedings revealed a significant deviation from these instructions.

Moses discovered that a sin offering goat had been burned rather than eaten. On that specific day, three different goats had been sacrificed: a special offering for the eighth day, a goat brought by Nahshon of the tribe of Judah, and the additional offering for the new month. The primary approach among commentators is that the burned sacrifice was the new month offering, as it was a permanent, generational requirement, unlike the other two which were unique, one-time offerings for the dedication [רמב״ן, רש״י, ספורנו, מזרחי, מלבי״ם, רש ר הירש]. Conversely, a straightforward reading of the events suggests it may have been the special goat of the eighth day [שד״ל, חזקוני, העמק דבר]. Moses conducted a thorough, dual inquiry, questioning why one specific goat was burned while the other two were either eaten or set aside. To Moses, this presented a profound contradiction. If Aaron and his sons believed their mourning prohibited them from eating sacred offerings, they should have burned all three. If they understood that a special ruling permitted them to eat despite their mourning, they should have consumed them all [מזרחי, תורה תמימה, מלבי״ם, ברכת אשר, שפתי כהן].

The conflict between Moses and Aaron stemmed from fundamentally different understandings of the boundaries of the special permission granted that day. Moses maintained that the allowance to eat was absolute, applying uniformly to all the day's sacrifices without exception [אור החיים, חומש קה״ת]. Aaron and his sons, however, drew a clear legal distinction. They ate the one-time dedication offerings but adopted a stricter stance regarding the permanent new month offering. Because it was a standard generational sacrifice, they felt the usual prohibition against mourners eating sacred food remained intact, prompting them to burn it [רש״י, רמב״ן, אור החיים]. Alternatively, another perspective suggests the goat was not burned due to mourning at all, but rather because it had inadvertently become ritually impure while the priests waited for evening to consume it [רמב״ן, רש״י, ברטנורא, דברי דוד].

Upon discovering the burned offering, Moses directed his anger specifically at Eleazar and Ithamar. This raises a question, as Aaron was the supreme authority and the one who ultimately made the decision. The accepted explanation is that Moses acted out of respect for his older brother; he faced the sons and rebuked them, fully intending for the criticism to encompass Aaron as well [רש״י, מזרחי, תורה תמימה, משכיל לדוד]. It is also possible that Moses targeted the sons because, as the younger priests, they physically performed the sacrificial labor [ביאור שטיינזלץ], or because he assumed they had acted independently without their father's knowledge [ביאור יש״ר].

The focus on Eleazar and Ithamar as the surviving sons serves several purposes. Practically, it excludes Aaron's grandson Phinehas, who had not yet been anointed to the priesthood [תורה תמימה, מלבי״ם]. More deeply, it conveys a hidden rebuke rooted in Moses's profound concern: having just survived the tragedy that claimed their brothers, they needed to be exceptionally meticulous with the sacred laws to avoid suffering a similar fate [רלב״ג, אלשיך, העמק דבר]. Some interpret this focus on their survival as an expression of severe frustration, as if Moses, in his intense anger, felt they were acting as though they too should not have survived [אור החיים, צרור המור]. Ultimately, Moses concluded his confrontation by demanding an active response. He instructed them to answer his claims, deliberately giving them the platform to explain their actions without fearing they were disrespecting him as their teacher [רש״י, מזרחי, שפתי חכמים, מלבי״ם].
