Leviticus 4:2

If a soul shall sin through ignorance - That is, if any man shall do what God has forbidden, or leave undone what God has commanded, through ignorance of the law relative to these points; as soon as the transgression or omission comes to his knowledge, he shall offer the sacrifice here prescribed, and shall not suppose that his ignorance is an excuse for his sin. He who, when his iniquity comes to his knowledge, refuses to offer such a sacrifice, sins obstinately and wilfully, and to him there remains no other sacrifice for sin - no other mode by which he can be reconciled to God, but he has a certain fearful looking for of judgment - which shall devour such adversaries; and this seems the case to which the apostle alludes, Hebrews 10:26, etc., in the words above quoted. There have been a great number of subtle questions started on this subject, both by Jews and Christians, but the above I believe to be the sense and spirit of the law.

If a soul shall sin - The sin-offering was a new thing, instituted by the Law. The older kinds of sacrifice Leviticus 2:1; Leviticus 3:1 when offered by individuals were purely voluntary: no special occasions were prescribed. But it was plainly commanded that he who was conscious that he had committed a sin should bring his sin-offering. In the abridged rules for sin-offerings in Numbers 15:22-31, the kind of sin for which sin-offerings were accepted is contrasted with that which cut off the perpetrator from among his people (compare Leviticus 4:22 with Leviticus 4:30). The two classes are distinguished in the language of our Bible as sin through ignorance and presumptuous sin. The distinction is clearly recognized in Psalm 19:12-13 and Hebrews 10:26-27. It seems evident that the classification thus indicated refers immediately to the relation of the conscience to God, not to outward practices, nor, immediately, to outward actions.

The presumptuous sinner, literally he who sinned "with a high hand," might or might not have committed such a crime as to incur punishment from the civil law: it was enough that he had with deliberate purpose rebelled against God (see Proverbs 2:13-15), and ipso facto was "cut off from among his people" and alienated from the divine covenant (see Leviticus 7:20; Exodus 31:14; compare Matthew 12:31; 1 John 5:16). But the other kind of sin, that for which the sin-offering was appointed, was of a more complicated nature. It appears to have included the entire range of "sins, negligences and ignorances" for which we are accustomed to ask forgiveness. sin-offerings were required not only when the conscience accused the offender of having yielded to temptation, but sometimes for what were breaches of the Law committed strictly in ignorance Leviticus 4:13, Leviticus 4:23, Leviticus 4:28; Leviticus 5:17, and sometimes on account of ceremonial pollution. They are thus to be regarded as protests against everything which is opposed to the holiness and purity of the divine Law. They were, in short, to be offered by the worshipper as a relief to the conscience whenever he felt the need of atonement.

Sin through ignorance - Sin through error; that is, through straying from the right way. See Psalm 119:67; Ecclesiastes 5:6.

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, Leviticus 16:30.

Through ignorance — Or, error, either not knowing his act to be sinful, as appears by comparing Leviticus 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, Psalms 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 verses.
