ויקרא, פרק ט׳, פסוק ז׳

On the eighth day of the Tabernacle's inauguration, following a week where Moses served as the acting priest and instructor, the moment arrives for Aaron to assume his sacred duties. Moses passes the baton of spiritual leadership to his brother, instructing him to step forward and perform the sacrifices that will achieve atonement for himself and the nation. The primary approach among commentators focuses on this physical command to approach the altar. Until this moment, Aaron held the status of an apprentice or a layman, strictly forbidden from drawing near. Now, Moses grants him the official authorization to approach the northern side of the altar, the designated area for slaughtering the sacrifices [רמב״ן, רבנו בחיי, חזקוני, שטיינזלץ, רד״צ הופמן].

Beneath this formal transition lies a profound psychological and spiritual struggle. Aaron is hesitant, overwhelmed by shame and fear. The singular failure of his life, his involvement with the Golden Calf, remains constantly etched in his mind. The trauma of that event is so intense that he imagines the horns of the altar taking the shape of a calf, or feels an accusing presence presenting the calf before him to instill doubt about his worthiness for the priesthood [רש״י, רמב״ן, מזרחי, רא״ש, דעת זקנים, הדר זקנים, צאינה וראינה]. Furthermore, Aaron worries that ascending to such a high station might lead him to arrogance. He also fears that his participation in the sin fundamentally disqualifies him from serving as a spiritual defender for the Israelites, reasoning that a prosecutor cannot suddenly become an advocate [משכיל לדוד, פרדס יוסף].

Recognizing this deep reluctance, Moses offers profound encouragement, asking his brother why he is so ashamed when this is precisely why he was chosen. Moses explains that it is exactly this humility, shame, and brokenheartedness that make Aaron the most fitting candidate for the role of High Priest. The constant awareness of his past failure will ensure that he never becomes haughty, and it will prevent any members of the tribe of Levi from challenging his appointment [פרדס יוסף, פני דוד, אדרת אליהו (הבן איש חי)]. Moses urges Aaron to set his shame aside and approach the sacred work with confidence, revealing that the very shame he feels is what ultimately achieves his atonement [רמב״ן, מלבי״ם, העמק דבר, פני דוד].

Aaron is then instructed to prepare his personal sacrifices, consisting of a two-year-old calf for a sin offering and a ram for a burnt offering. The order of these offerings is deliberate. The sin offering must precede the burnt offering because one must first achieve purification and cleanse the actual sin before presenting a burnt offering as a spiritual gift to God [רש״י, מזרחי, שפתי כהן].

The instruction for Aaron to atone for both himself and the people raises a question about how his personal sacrifice benefits the nation. Commentators agree on the principle that the innocent must atone for the guilty; the priest must first achieve his own purity before he can effectively seek forgiveness for the public [רמב״ן, אבן עזרא, חזקוני, רא״ש, דעת זקנים]. Beyond this legal principle, there is a deep mutual dependence between Aaron and the Israelites. The people were the ones who pressured Aaron into creating the Golden Calf, giving them a core role in his failure. Consequently, the moment Aaron achieves his own atonement, the people are simultaneously forgiven for their part in causing his stumble [אור החיים, כלי יקר, רש״ר הירש, פרדס יוסף]. This dynamic highlights the intimate connection between the nation and its leaders, where a leader's corruption implicates the people, and his redemption brings about their healing [כלי יקר].

Finally, Aaron is directed to prepare the sacrifices of the people, which include a goat for a sin offering alongside a one-year-old calf and a lamb for a burnt offering. The precise differences between Aaron's offerings and those of the people reveal the distinct nature of their transgressions. Aaron sinned solely through his actions, and therefore he brings a calf as a sin offering. In contrast, the people harbored internal thoughts of idolatry, requiring them to bring a calf as a burnt offering, which specifically atones for the sinful thoughts of the heart [כלי יקר, חתם סופר]. The separation of their respective sacrifices also serves to emphasize a difference in the age of the animals. While Aaron's specific calf was two years old, the general rule is that an unspecified calf, such as the one brought by the nation, is always exactly one year old [רש״י, מזרחי, משכיל לדוד, גור אריה].
