During the emotional consecration ceremony of Aaron as the High Priest, a highly unique ritual takes place. Blood from the sacrifice is placed on three specific parts of the right side of his body: the bottom of the earlobe, the thumb, and the big toe [ביאור שטיינזלץ, רבנו בחיי].
The act of slaughtering this specific sacrifice is marked by a rare musical note in the traditional reading that denotes a lingering delay or hesitation. This pause carries several layers of meaning. Practically, Moses may have deliberately prolonged the slaughtering process to extract the large quantity of blood necessary for the extensive sprinkling on these body parts. Conceptually, this delay emphasizes the immense importance of the ram of consecration, elevating it as the central sacrifice of the entire ceremony, even more significant than the sin and burnt offerings [ברכת אשר על התורה]. On a lighter note, some see this lingering as a humorous nod to the fact that the one who slaughters the animal often also serves as the community's prayer leader, a role known for drawing out melodies [פרדס יוסף].
The primary approach among commentators reveals a profound parallel between the structure of the Tabernacle, the universe, and the human body, which is viewed as a miniature universe. The cosmos is divided into three realms: the world of angels representing intellect, the world of the heavenly spheres representing constant movement, and the lower earthly world representing physical nature. The High Priest's role is to bridge all these realms through his service. He is anointed with blood, which represents the atonement of the soul [אבן עזרא], on three body parts that correspond to these cosmic levels. The ear, located on the head, symbolizes the realm of intellect and angels. The hand, situated in the center of the body near the constantly beating heart, represents the ever-moving heavenly spheres. Finally, the foot symbolizes the lower, material world [רבנו בחיי, תולדות יצחק, צאינה וראינה]. When a person recognizes that they contain all these worlds within themselves, this awareness elevates them and serves as a powerful safeguard against sin [צאינה וראינה].
Beyond this cosmic symbolism, the selection of these specific body parts carries a deeply practical and moral message for the High Priest as the leader of the people. The ear is anointed to remind him to listen carefully and strictly observe the Commandments [תולדות יצחק], while also remaining constantly attentive to the needs and struggles of the public. The hand is anointed to ensure precision in his Temple service, but also to stress that a true leader cannot sit idle; he must be a man of action dedicated to his community. The foot is anointed to remind him to walk with humility and avoid entering holy spaces at inappropriate times [תולדות יצחק]. Furthermore, it teaches him that he must never stagnate. A leader must always be in a state of spiritual movement and growth, because a person who is not moving forward is inevitably sliding backward [פרדס יוסף].
Additionally, placing the blood on the thumb serves as a spiritual safeguard, protecting the High Priest from harm and the evil eye [פרדס יוסף]. In relation to the fingers, commentators reflect on the wonders of the human body's design, noting that the five fingers were created precisely to serve the five senses. For instance, the thumb is designed to serve the mouth and the sense of taste, while the smallest finger serves the ear. This intricate design stands as a testament to the fact that God created humanity with profound wisdom, ensuring that no part of the body is without purpose [רבנו בחיי, תולדות יצחק].
