Numbers 17:2

Of every one — Not of every person, but of every tribe. A rod — That staff, or rod, which the princes carried in their hands as tokens of their dignity and authority. Every man's name — Every prince's: for they being the first — born, and the chief of their tribes might above all others pretend to the priesthood, if it was communicable to any of their tribes, and besides each prince represented all his tribe: so that this was a full decision of the question. And this place seems to confirm, that not only Korah and the Levites, but also those of other tribes contested with Moses and Aaron about the priesthood, as that which belonged to all the congregation they being all holy.
