And all the congregation . . . —That is, the elders who represented the people, whom Moses summoned (see Leviticus 9:1), and as many of the people as could find room assembled before the sanctuary in the court-yard to witness the newly-installed priests officiating for the first time.

Le 9:1-24. The Priests' Entry into Office.

1-7. Moses called … Take thee a young calf for a sin offering—The directions in these sacred things were still given by Moses, the circumstances being extraordinary. But he was only the medium of communicating the divine will to the newly made priests. The first of their official acts was the sacrifice of another sin offering to atone for the defects of the inauguration services; and yet that sacrifice did not consist of a bullock—the sacrifice appointed for some particular transgression, but of a calf, perhaps not without a significant reference to Aaron's sin in the golden calf [Ex 32:22-24]. Then followed a burnt offering, expressive of their voluntary and entire self-devotement to the divine service. The newly consecrated priests having done this on their own account, they were called to offer a sin offering and burnt offering for the people, ending the ceremonial by a peace offering, which was a sacred feast. This injunction, "to make atonement for himself and for the people" (Septuagint, "for thy family"), at the commencement of his sacred functions, furnishes a striking evidence of the divine origin of the Jewish system of worship. In all false or corrupt forms of religion, the studied policy has been to inspire the people with an idea of the sanctity of the priesthood as in point of purity and favor with the Divinity far above the level of other men. But among the Hebrews the priests were required to offer for the expiation of their own sins as well as the humblest of the people. This imperfection of Aaron's priesthood, however, does not extend to the gospel dispensation: for our great High Priest, who has entered for us into "the true tabernacle," "knew no sin" (Heb 10:10, 11).

and all the congregation drew near, and stood before the Lord; that is, the elders of Israel, who were called together, Leviticus 9:1, the heads of the tribes who represented the people; as many as well could be admitted into the court no doubt were, to be spectators of Aaron and his sons officiating first in their new office, and to see their own sacrifices offered; and they stood over against where was the symbol of the divine Presence; and the Targum of Jonathan says, they stood with a perfect heart; and no doubt but they were heartily sincere and upright in their sacrifices, as they had been in their donations toward the building the tabernacle, and providing things belonging to it; and they stood with all humility, reverence, and devotion.
