במדבר, פרק ד׳, פסוק ל״ז

The final tally of the Kohathite families provides more than just a census number. It captures the true nature of their unique responsibilities in the Tabernacle and traces the exact chain of command that led to their appointment. The Kohathites are identified specifically as those who perform service. This phrasing highlights their role as singers, a duty classified as actual service within the sanctuary. This stands in sharp contrast to the family of Merari, who were tasked merely with carrying loads and standing guard. Those physical tasks, while essential, do not meet the strict definition of service [צפנת פענח].

The counting was conducted by both Moses and Aaron, yet the directive is described as coming from God through Moses. Aaron joined the counting process not because of a direct divine order, but because Moses applied his own logical deduction. Moses noticed that in other situations, such as the arrangement of the tribal camps, God addressed both of them. Applying this logic, Moses included Aaron in this census as well. The specific detail that this was accomplished through Moses highlights that Aaron's involvement was a result of Moses's own understanding and application of God's word [העמק דבר].

A closer look at the census records reveals a pattern in how the different families are addressed. The confirmation that the command came through Moses concludes the counts for the Kohathites and the Merarites, but it is absent from the count of the Gershonites. This difference stems from how God initially delivered the instructions for each group. For the Kohathites, the earlier instructions were spoken to both Moses and Aaron, making it necessary to clarify later that the primary prophecy was given directly to Moses. Regarding the Merarites, their section lacked an opening statement that God spoke to Moses, so it was essential to confirm at the end that their counting was indeed directed by God through Moses. The Gershonites, however, had an opening command directed exclusively to Moses without mentioning Aaron. Since his sole authority was clear from the start, there was no need to repeat it at the conclusion [רא״ש, דעת זקנים].
