7 And Moses said unto Aaron, Go to the altar, and offer thy sin-offering, and thy burnt-offering, and make atonement for thyself, and for the people; and offer the offering of the people, and make atonement for them, as Jehovah has commanded.
8 And Aaron went to the altar and slaughtered the calf of the sin-offering which was for himself; 9 and the sons of Aaron presented the blood to him, and he dipped his finger in the blood, and put [it] on the horns of the altar, and poured out the blood at the bottom of the altar. 10 And the fat, and the kidneys, and the net above the liver, of the sin-offering, he burned on the altar, as Jehovah had commanded Moses. 11 And the flesh and the skin he burned with fire outside the camp.

Commentary on Leviticus 9:1-21
(Read Leviticus 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.
