A young calf - A bull calf, which might have been what we should call a yearling ox.

Take thee a young calf, etc. - As these sacrifices were for Aaron himself, they are furnished by himself and not by the people, for they were designed to make atonement for his own sin. See Leviticus 4:3. And this is supposed by the Jews to have been intended to make an atonement for his sin in the matter of the golden calf. This is very probable, as no formal atonement for that transgression had yet been made.

And he said unto Aaron,.... In the presence of the people of Israel:

take thee a young calf for a sin offering; one not exceeding a year old, as in Leviticus 9:3 but this was not for the sin of making the calf only, to which the Jewish writers restrain it, but for all other sins of his, which it was necessary should be expiated before he offered sacrifices for the sins of others:

and a ram for a burnt offering; being a strong and innocent creature, was a proper emblem of Christ, the Lamb of God, that takes away by his sacrifice the sins of men:

without blemish; this character belongs, as Aben Ezra observes, both to the calf and ram, which were both to be without spot, and so proper types of Christ the Lamb without spot and blemish, free both from original and actual sin:

and offer them before the Lord; on the altar of burnt offering, which stood in the court of the tabernacle near where Jehovah was, to whom every sacrifice for sin was to be offered, being committed against him, and whose justice must be satisfied for it.

And he said unto Aaron, Take thee a young calf for a {b} sin offering, and a ram for a burnt offering, without blemish, and offer them before the LORD.

(b) Aaron enters into the possession of the priesthood: and offers the four principal sacrifices, the burnt offering, the sin offering, the peace offering, and the meat offering.

9:2 For a sin - offering - For himself and his own sins, which was an evidence of the imperfection of that priesthood, and of the necessity of a better. The Jewish writers suggest, that a calf was appointed, to remind him of his sin in making the golden calf. Thereby he had rendered himself for ever unworthy of the honour of the priesthood: on which he had reason to reflect with sorrow and shame, in all the atonements he made.

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.
