Matthew Poole and continuators on Leviticus 9:23

23 And Moses and Aaron went into the tabernacle of the congregation, and came out, and blessed the people : and the glory of the LORD appeared unto all the people.

Who went in with Aaron to direct him, and to see him perform those parts of his office which were to be done in the holy place, about the lights, and the table of shew-bread, and of the altar of Incense, upon which part of the blood of the sacrifices now offered was to be sprinkled according to the law, Levit. 4. 7, 16, 17.

(i. e.) Prayed to God for his blessing upon the people, as this phrase is explained, Numb. 6. 23, &c. and particularly for his gracious acceptation of these and all succeeding sacrifices, and for his signification thereof by some extraordinary token, which accordingly happened.

Either a miraculous brightness shining from the cloudy pillar, as Exod. 16. 10. Numb. 14. 10. Or a glorious and visible discovery of Gods gracious presence and acceptance of the present Ministery and service, as it follows.
