The dedication of the Levites for service in the Tabernacle marks a profound moment of transferring authority and delegating power. This event redefines the spiritual roles within the nation, establishing the Levites as the official representatives of the entire people in matters of holiness.
The act of laying hands upon the Levites carries a dual significance. On one level, it compares the Levites to a public sacrifice that brings atonement for the nation. Just as a person bringing an offering presses their hands upon the animal, the congregation sets the Levites apart, dedicating them to the service of the Tent of Meeting and the study of Torah [העמק דבר, ביאור שטיינזלץ]. On another level, this action serves as a formal appointment and a granting of authority. By pressing their hands upon them, the nation declares that the Levites act as their agents, taking their place in the holy service. This mirrors the way Moses placed his hands upon Joshua to pass on leadership and authority [רש ר הירש, חזקוני, ביאור שטיינזלץ].
The primary approach among commentators is that this was an actual, physical placing of hands. While a minority view suggests the appointment was purely verbal—similar to how later sages were ordained—this idea is generally rejected. The explicit details of the event firmly indicate a tangible, physical action using the hands [נחל קדומים].
A practical question arises regarding who exactly performed this action, as it would be impossible for the entire nation to physically lay their hands on the Levites. One perspective suggests that representatives of the Israelites, such as members of the high court, community heads, or great leaders, acted on behalf of the entire public. These representatives may have placed their hands specifically on the heads of the Levite leaders [שד״ל, העמק דבר, ביאור שטיינזלץ]. Conversely, another approach identifies the participants specifically as the firstborn Israelites. Because the Levites were taking over the Tabernacle duties previously meant for the firstborns, serving as an atonement in their stead, each firstborn personally laid his hands upon the specific Levite who was stepping into his place [חזקוני, ביאור שטיינזלץ, ברכת אשר על התורה].
