And Moses said unto the congregation
Having convened them, he opened to them the reason of their being
called together, which was not done of himself, but by divine
direction: this [is] the thing which the Lord commanded to
namely, what follows, concerning the consecration of Aaron and
his sons to be priests, and the investiture of them with that
office, attended with various rites and ceremonies to be
performed, of which they were to be witnesses.
