ויקרא, פרק ח׳, פסוק י״ד

The ordination period, during which Aaron and his sons are sanctified for the priesthood, involves a series of highly detailed sacrifices. Even though this ceremony is a one-time event, the extensive detail highlights the importance of human partnership in completing God's creation. It also serves as an eternal lesson on the necessity of absolute precision when fulfilling God's commandments. God expects those closest to Him to perform their duties with exactness, just as He instructed. During this ceremony, Moses serves as the officiant. Since he is not a regular priest, a question arises regarding his attire in the holy space. He performs these duties wearing a plain white tunic [ברכת אשר על התורה].

As part of the process, a bull is brought forward. The original instruction given earlier regarding the setup of the Tabernacle simply referred to this animal as a bull, yet during the actual event, it is specifically designated as a sin offering [חזקוני, פירושי רד צ הופמן, מלבי״ם]. Commentators offer a few reasons for this shift. One approach explains that now, as the action is being carried out, the exact classification of the sacrifice is detailed [חזקוני, מלבי״ם]. Another perspective suggests a historical shift: the original instruction was given before the sin of the Golden Calf, making the mention of a sin offering unnecessary at the time, whereas the actual event takes place after the sin [מלבי״ם]. Additionally, a legal perspective notes that the general instruction omitted the specific name to prevent future confusion regarding its classification, but at the moment of the actual sacrifice, Moses explicitly stated its purpose [מלבי״ם].

Although it functions as a sin offering and is burned outside the camp, similar to the special sin offerings brought by a High Priest or the entire community, it does not follow the standard rules for those sacrifices. Because of this, it is understood to be a unique, temporary directive meant exclusively for this specific ordination ceremony [מלבי״ם].

Before the sacrifice is processed, Aaron and his sons place both of their hands on the animal's head. This action is standard for anyone bringing a personal sacrifice [ביאור שטיינזלץ]. They perform this step because they are the direct owners of this specific offering [אדרת אליהו, מלבי״ם]. Although five individuals share ownership of this single animal, the action is recorded in the singular form. This indicates that they do not place their hands on the animal simultaneously. Instead, each person performs the action individually and steps away, one after the other [מלבי״ם].
