4:2 Speak unto the children of Israel, saying, If a soul shall sin through {a} ignorance against any of the commandments of the LORD [concerning things] which ought not to be done, and shall do against any of them:
(a) That is, of negligence or ignorance, especially in the ceremonial law: for otherwise the punishment for a crime is determined according to the transgression, Nu 15:22.
4:2 If a soul sin - This must necessarily be understood of more than common daily infirmities; for if every such sin had required an offering, it had not been possible either for most sinners to bear such a charge, or for the altar to receive so many sacrifices, or for the priests to manage so infinite a work. And for ordinary sins, they were ceremonially expiated by the daily offering, and by that on the great day of atonement, Lev 16:30. Through ignorance - Or, error, either not knowing his act to be sinful, as appears by comparing Lev 4:13,14, or not considering it, but falling into sin thro' the power of some sudden passion or temptation, as the Hebrew word signifies, Psa 119:67. Things which ought not to be done - The words may be rendered, in or about every, or any of the commandments of the Lord which should not be done; or, which concern things that should not be done, namely, in any negative commands. (And there is great reason why a sacrifice should be more necessary for these, than for other sins, because affirmative precepts do not so strictly and constantly bind men as the negative do.) Then he shall offer according to his quality, which is here to be understood out of the following verse s.
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.
