Numbers 8:9

And thou shalt bring the Levites before the tabernacle of the congregation,.... Not without it, but within it, in the court of the tabernacle, at least at the door of it, where stood the altar of burnt offering, on which sacrifices for them were now to be offered:

and thou shalt gather the whole assembly of the children of Israel together; the heads of the tribes, and elders of the people, as Aben Ezra interprets this phrase in Leviticus 8:3; where the whole congregation is said to be assembled at the consecration of the priests, as here at the consecration of the Levites, having a concern therein, as well as to be spectators and witnesses of this solemn affair; and no doubt as many of them as could conveniently assemble at the door of the tabernacle did, though every individual of that large body of people could not possibly do it.
