שמות, פרק מ׳, פסוק י״ג

The preparation of the High Priest involves a careful and deliberate sequence of events to ready him for divine service. The process of dedicating Aaron to the High Priesthood consists of unique steps that clearly distinguish his initiation from that of his sons [קאסוטו]. This procedure moves through distinct phases, starting with dressing him in holy garments that are crafted exclusively for his role.

Following the donning of these special clothes, the main phase of the dedication takes place through anointing and sanctification. Aaron alone is anointed for the primary priestly position, and it is through these specific physical actions that his holiness is established [שטיינזלץ, קאסוטו]. The completion of this process marks a definitive transition, establishing that from this point forward, he is fully worthy and prepared to serve as a priest before God [שטיינזלץ]. Only after Aaron’s distinct and personal dedication is entirely finalized does the focus shift to the steps required for initiating his sons [קאסוטו].
