The treatment of the blood was special in the sin-offerings. In the inferior sin-offerings it was smeared on the horns of the altar of burnt-offering Leviticus 4:25, Leviticus 4:30, Leviticus 4:34, while in this offering for the high priest, and in that for the nation, the high priest himself sprinkled the blood seven times within the tabernacle and smeared it on the horns of the altar of incense Leviticus 4:6-7, Leviticus 4:17-18. The different modes of sprinkling appear to have marked successive degrees of consecration in advancing from the altar of burnt-offering to the presence of Yahweh within the veil.

And the priest that is anointed shall take of the bullock's blood,.... Let out and received into a basin; this he did himself, and not another, for he offered for himself, and the blood was to make atonement for him:

and bring it to the tabernacle of the congregation; out of the court where the bullock was slain, into the holy place, where were the vail that divided between the holy of holies, and the altar of sweet incense, after mentioned.

And the priest that is anointed shall take of the bullock's blood, and bring it to the tabernacle of the congregation:

4:5 To the tabernacle - Into the tabernacle; which was not required nor allowed in any other sacrifice, possibly to shew the greatness of the high - priest's sin, which needed more than ordinary diligence in him, and favour from God to expiate it.

4:1-12 Burnt-offerings, meat-offerings, and peace-offerings, had been offered before the giving of the law upon mount Sinai; and in these the patriarchs had respect to sin, to make atonement for it. But the Jews were now put into a way of making atonement for sin, more particularly by sacrifice, as a shadow of good things to come; yet the substance is Christ, and that one offering of himself, by which he put away sin. The sins for which the sin-offerings were appointed are supposed to be open acts. They are supposed to be sins of commission, things which ought not to have been done. Omissions are sins, and must come into judgment: yet what had been omitted at one time, might be done at another; but a sin committed was past recall. They are supposed to be sins committed through ignorance. The law begins with the case of the anointed priest. It is evident that God never had any infallible priest in his church upon earth, when even the high priest was liable to fall into sins of ignorance. All pretensions to act without error are sure marks of Antichrist. The beast was to be carried without the camp, and there burned to ashes. This was a sign of the duty of repentance, which is the putting away sin as a detestable thing, which our soul hates. The sin-offering is called sin. What they did to that, we must do to our sins; the body of sin must be destroyed, Ro 6:6. The apostle applies the carrying this sacrifice without the camp to Christ, Heb 13:11-13.
