A kid of the goats - A shaggy he-goat. See Leviticus 4:23 note.

Take ye a kid - In Leviticus 4:14 a young bullock is commanded to be offered for the sin of the people; but here the offering is a kid, which was the sacrifice appointed for the sin of the ruler, Leviticus 4:22, Leviticus 4:23, and hence some think that the reading of the Samaritan and the Septuagint is to be preferred. Speak unto the Elders of Israel, these being the only princes or rulers of Israel at that time; and for them it is possible this sacrifice was designed. It is however supposed that the sacrifice appointed Leviticus 4:14 was for a particular sin, but this for sin in general; and that it is on this account that the sacrifices differ.

And unto the children of Israel thou shalt speak,.... That is, Aaron should speak to them, for being now high priest, Moses had no more to do with the sacrifices of the people, but it was incumbent on Aaron to call upon them to bring them to him such as the Lord by this law required of them:

saying, take ye a kid of the goats for a sin offering; this creature fitly represented Christ as made sin, and an offering for sin, in the room of his people:

and a calf, and a lamb; both of them, as before observed, were proper emblems of Christ in his strength and innocence, sometimes called the fatted calf, and frequently the Lamb of God, Luke 15:23 John 1:29,

both of the first year, without blemish, for a burnt offering; denoting the tenderness of Christ, his spotless purity, and painful sufferings.

And unto the children of Israel thou shalt speak, saying, Take ye a kid of the goats for a sin offering; and a calf and a lamb, both of the first year, without blemish, for a burnt offering;

9:3 A sin - offering - For the people, for whose sin a young bullock was required, Lev 4:15, but that was for some particular sin; this was more general for all their sins. Besides, there being an eye here to the priest's consecration and entrance into his office, it is no wonder if there be some difference in these Sacrifices from those before prescribed.

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.
