9:1 And it came to pass on the {a} eighth day, [that] Moses called Aaron and his sons, and the elders of Israel;
(a) After their consecration: for the seven days before, the priests were consecrated.
9:1 On the eighth day - Namely, from the day of his consecration, or when the seven days of his consecration were ended. The eighth day is famous in scripture for the perfecting and purifying both of men and beasts. See Lev 12:2,3 14:8,9,10 15:13,14 22:27. And the elders of Israel - All the congregation were called to be witnesses of Aaron's installment into his office, to prevent their murmurings and contempt; which being done, the elders were now sufficient to be witnesses of his first execution of his office.
9:1-21 These many sacrifices, which were all done away by the death of Christ, teach us that our best services need washing in his blood, and that the guilt of our best sacrifices needs to be done away by one more pure and more noble than they. Let us be thankful that we have such a High Priest. The priests had not a day's respite from service allowed. God's spiritual priests have constant work, which the duty of every day requires; they that would give up their account with joy, must redeem time. The glory of God appeared in the sight of the people, and owned what they had done. We are not now to expect such appearances, but God draws nigh to those who draw nigh to him, and the offerings of faith are acceptable to him; though the sacrifices being spiritual, the tokens of the acceptance are spiritual likewise. When Aaron had done all that was to be done about the sacrifices, he lifted up his hands towards the people, and blessed them. Aaron could but crave a blessing, God alone can command it.
