ויקרא, פרק ט׳, פסוק י״ב

Following the completion of the Sin Offering, the service in the Tabernacle moves to the Burnt Offering. This stage is marked by a practical collaboration between Aaron and his sons, where every physical movement reflects the core purpose and specific rules of the offering.

Aaron, the High Priest, personally carried out the slaughtering of the animal [פירושי רד צ הופמן, ביאור שטיינזלץ]. However, his sons were actively involved in handling the blood. Their participation was not a random addition but a deliberate educational process, meant to train them in the holy service by working alongside their father on his offering [ספורנו].

When it came time to transfer the blood, the sons presented it exactly at the moment it was needed [רש״י, אבן עזרא]. The primary approach among commentators notes a careful distinction between how the sons handled the blood for the Sin Offering versus the Burnt Offering. During the Sin Offering, Aaron only needed to dip his finger into the blood, so it was enough for his sons to simply hold the bowl close to him while keeping it in their own hands. The Burnt Offering, however, required Aaron to throw the blood directly from the vessel against the Altar. Because of this, the sons had to physically hand the bowl over, placing it directly into Aaron's hands so he could complete the task [העמק דבר, הכתב והקבלה, פירושי רד צ הופמן].

Beyond the practical mechanics, there is a spiritual concept behind this total physical transfer. Unlike the Sin Offering, which is directed downward, the Burnt Offering is elevated entirely to God. By handing the blood completely over to Aaron to be thrown all around the Altar, the action vividly expresses the total upward elevation and dedication of the offering [שפתי כהן].
