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.
4:13-21 If the leaders of the people, through mistake, caused them to err, an offering must be brought, that wrath might not come upon the whole congregation. When sacrifices were offered, the persons, on whose behalf they were devoted, were to lay their hands on the heads of the victims, and to confess their sins. The elders were to do so, when the sacrifices were offered for the whole congregation. The load of sin was supposed then to be borne by the guiltless animal. When the offering is completed, it is said, atonement is made, and the sin shall be forgiven. The saving of churches and kingdoms from ruin, is owing to the satisfaction and mediation of Christ.
4:22-26 Those who have power to call others to account, are themselves accountable to the Ruler of rulers. The sin of the ruler, committed through ignorance, must come to his knowledge, either by the check of his own conscience, or by the reproof of his friends; both which even the best and greatest, not only should submit to, but be thankful for. That which I see not, teach thou me, and, Show me wherein I have erred, are prayers we should put up to God every day; that if, through ignorance, we fall into sin, we may not through ignorance abide in it.
4:27-35 Here is the law of the sin-offering for a common person. To be able to plead, when charged with sin, that we did it ignorantly, and through the surprise of temptation, will not bring us off, if we have no interest in that great plea, Christ hath died. The sins of ignorance committed by a common person, needed a sacrifice; the greatest are not above, the meanest are not below Divine justice. None, if offenders, were overlooked. Here rich and poor meet together; they are alike sinners, and welcome to Christ. From all these laws concerning the sin-offerings, we may learn to hate sin, and to watch against it; and to value Christ, the great and true Sin-offering, whose blood cleanses from all sin, which it was not possible that the blood of bulls and of goats should take away. For us to err, with the Bible in our hands, is the effect of pride, sloth, and carelessness. We need to use frequent self-examination, with serious study of the Scriptures, and earnest prayer for the convincing influences of God the Holy Spirit; that we may detect our sins of ignorance, repent, and obtain forgiveness through the blood of Christ.
