Those are the duties of the Gershonite clans for the Tent of Meeting; they shall attend to them under the direction of Ithamar son of Aaron the priest.
Ohr HaChaim on Numbers 4:28 — EXTRA.
זאת עבדת —\ldots עבודתם באהל מועד תחת יד איתמר.
English: “This is the service” — \ldots their service in the Tent of Meeting under the hand of Isamar.
Custom
The Gershonite labor remains under priestly supervision so that even the secondary burdens stay within the framework of kedushah.
