7 And Moses said to Aaron, Come near to the altar and make your sin-offering and your burned offering to take away your sin and the sin of the people, and make the people's offering to take away their sin; as the Lord has given orders.
8 So Aaron came near to the altar and put to death the ox for the sin-offering for himself; 9 And the sons of Aaron gave him the blood and he put his finger in the blood and put it on the horns of the altar, draining out the blood at the base of the altar; 10 But the fat and the kidneys and the fat on the liver of the sin-offering were burned by him on the altar as the Lord gave orders to Moses. 11 And the flesh and the skin were burned with fire outside the tent-circle;

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.
