Take Aaron and his sons with him, and the garments, and the anointing oil, and a bullock for the sin offering, and two rams, and a basket of unleavened bread;
Take Aaron and his sons. The consecration of Aaron and his sons had been ordered long before (Exodus 29:1-46), but it is now described with all the details of the ceremonial, since it was gone through after the tabernacle was completed, and the regulations for the various sacrifices enacted. In reference to this, it was manifestly expedient for the Israelite people to be satisfied that Aaron's appointment to the high dignity of the priesthood was not a personal intrusion nor a family arrangement between him and Moses; and nothing, therefore, could be a more prudent or necessary measure, for impressing a profound conviction of the divine origin and authority of the priestly institution, than to summon a general assembly of the people, and in their presence perform the solemn ceremonies of inauguration which had been prescribed by divine authority.
