ויקרא, פרק י׳, פסוק י״ח

In the midst of the Tabernacle's dedication day, overshadowed by the tragic deaths of Nadav and Avihu, Moses confronts Aaron and his remaining sons regarding the burning of the sin offering. His rebuke rests on a precise legal analysis of sacrificial laws, the location of the blood application, and the priests' unique state of mourning. The primary approach among commentators is that Moses presents a clear legal argument based on where the blood of the offering was placed. If this had been an inner sin offering, where the blood is applied inside the Sanctuary, the priests would indeed have been obligated to burn the meat. However, since this was an outer sin offering and its blood never entered the inner chamber, there was no justification for burning it. From this confrontation, a permanent law is derived: if the blood of an outer sin offering is accidentally brought into the Sanctuary, the offering is invalidated and must be burned [רלב״ג, מלבי״ם]. Moses also sought to dispel any misconception that this offering had to be burned simply because it was a public sacrifice atoning for idolatry [העמק דבר]. Furthermore, Moses investigated whether the priests had sprinkled the blood themselves while in a state of acute mourning, an act that would have invalidated the offering and necessitated its burning [חומש קה״ת].

To clarify his argument, Moses precisely defines the physical boundaries of where the blood should have been placed. He uses specific terminology to pinpoint the exact area of the Sanctuary, situated between the outer courtyard and the Holy of Holies. A broader term might have mistakenly implied the courtyard, which is also considered holy, while a term denoting the innermost area could have been confused with the Holy of Holies itself. By combining these descriptions, Moses leaves no room for error regarding the Sanctuary's exact space [תורה תמימה, מלבי״ם, ביאור יש״ר, נתינה לגר].

Since the meat had already been consumed by fire, Moses' instruction to eat it is universally understood not as a present command, but as a sharp rebuke: the priests should have eaten it rather than rushing to burn it [רש״י, מזרחי, שפתי חכמים, גור אריה, הופמן, ביאור יש״ר, אבן עזרא]. He insists that they were obligated to consume the offering despite being acute mourners on the very day of their tragic loss [רש״י, מזרחי, רש״ר הירש]. His phrasing emphasizes an absolute obligation rather than mere permission, contrasting with other sacrifices that are forbidden for consumption [מלבי״ם, אילת השחר]. It also specifically highlights that only an offering whose blood remained outside was permitted to be eaten, explicitly excluding any sacrifice whose blood was brought inside [מלבי״ם].

Moses roots his rebuke in a prior instruction. The primary approach among commentators is that he refers back to the laws of the meal offering. Moses drew a direct legal comparison: just as the meal offering is considered most holy and must be eaten in the courtyard even during mourning, the same rule applies to the sin offering. He deliberately avoided drawing this comparison from other parts of the sacrifices, such as the breast and thigh, because those are of a lesser holy status and are eaten outside the courtyard; therefore, they cannot serve as a precedent for most holy offerings [רש״י, מזרחי, שפתי חכמים, דברי דוד]. Interestingly, some explain that Moses emphasized that he personally commanded this, rather than God, because he deduced the ruling to eat the offering during mourning through his own logical comparison to the meal offering, without receiving an explicit divine directive [מלבי״ם, שפתי חכמים, ביאור יש״ר]. Conversely, others interpret his words simply as a declaration that he was conveying what he had been commanded directly by God [הופמן].
