ויקרא, פרק ח׳, פסוק כ״ח

The climax of the priestly consecration is marked by a unique transfer of the offerings. Taking the portions directly from the hands of Aaron and his sons and burning them to God cements their official entry into their new roles. This moment serves as a kind of royal feast celebrating their initiation into holy service [מלבי״ם]. The act of taking the offering directly from the offerers' hands is a procedure recognized in other contexts as well, such as the offering brought by a woman suspected of infidelity [רד״צ הופמן].

Throughout the seven days of consecration, Moses functioned as the acting priest, performing the service while wearing a simple white tunic [רש״י]. There are several reasons why his role in burning the offerings is specifically highlighted at this stage of the consecration ram, rather than earlier. In the initial stages, Aaron and his sons still lacked full atonement and were unfit to serve. However, once the blood of the preceding sacrifices had been dashed, they were technically ready to burn the fats themselves. The fact that Moses still performed the burning proves that he was commanded to serve as the exclusive priest for the entirety of the seven days [משכיל לדוד]. Additionally, the waving of the offering is a complex procedure that typically requires three priests. By performing it alone, Moses demonstrated that no one else was yet fit for the service [שפתי חכמים, גור אריה]. Alternatively, emphasizing Moses' actions simply prevents a misunderstanding; since the act of burning is described without explicitly naming who did it, one might mistakenly assume Aaron or his sons had performed it [לבוש האורה].

Regarding the white tunic Moses wore, he did not change his garments between different sacrifices as is the practice on the Day of Atonement. Instead, he performed all the services consecutively in the same white tunic he put on at the beginning of the day [דברי דוד]. The pure white color and the lack of a folded hem symbolize absolute simplicity, perfectly reflecting Moses' supreme and pristine spiritual level [גור אריה]. Furthermore, wearing this tunic indicates that Moses was functioning as a representative of Aaron and his sons at a temporary, private altar, rather than as God's representative at a permanent altar [חתם סופר].

The burning of this sacrifice presents a striking legal anomaly. The thigh of the animal was burned on the altar, even though elsewhere, the thigh of a peace offering is never burned but is given to the priests to eat [רש״י, מזרחי]. One explanation for this exception is that Moses was considered the owner of the sacrifice, and an owner is not permitted to eat this specific portion. At the same time, Aaron and his sons had not yet completed their priestly education and were therefore ineligible to eat it, leaving no choice but to burn the thigh on the altar [משכיל לדוד]. Another explanation suggests that God temporarily altered the standard law to create a clear distinction between Moses, a Levite serving only temporarily, and Aaron and his sons, who would receive these portions as an eternal right [שפתי חכמים].

The timing and placement of this burning relative to the earlier burnt offering is a matter of discussion. The primary approach among commentators is that it occurred chronologically after the burnt offering had already been completely consumed by the fire, rather than being placed physically on top of it [רש״י, מזרחי, שפתי חכמים, גור אריה, שטיינזלץ, דברי דוד]. However, other perspectives suggest that it was burned at the exact same time [חזקוני], or that it was laid directly on top of the burnt offering while the latter was still whole and burning, with no interruption between the two [אור החיים].

Ultimately, these sacrifices rise as a pleasing odor before God specifically because of their unique essence. They are consecration offerings, purposefully designed to educate, prepare, and dedicate the new priests for a lifetime of divine service [מלבי״ם].
