במדבר, פרק ג׳, פסוק כ״ז

As the breakdown of the tribe of Levi continues, the focus shifts to the four primary families descended from Kohath. Among these, the family of Amram carries special significance because it clarifies the distinct standing of Moses and Aaron within the nation.

The Amramite family specifically encompasses Moses and his sons. Detailing this group fulfills an earlier promise to present the full lineage of both Aaron and Moses, as the descendants of Moses are now officially accounted for [רשב״ם, חזקוני].

However, a sharp boundary is drawn between the two brothers. Aaron and his descendants are intentionally excluded from this count of the Amram family. This separation highlights a major shift in their spiritual roles. Aaron and his lineage were distinctly set apart for the priesthood to serve in the Holy of Holies. In contrast, Moses and his children did not receive this elevated priestly status; they remained regular members of the tribe of Levi and are simply counted alongside the rest of their relatives [חזקוני].
