Leviticus 4:2

“Speak unto the children of Israel, [saying], etc.] For this law concerning the sin offering, as the rest, only belonged to them, and such as were proselyted to them: if a soul should sin through ignorance; sin is from the soul, though committed by the body; it is the soul that sins, (<261804>Ezekiel 18:4) it includes, as Aben Ezra observes, both Israelites and proselytes; who sinned through ignorance either of the law, that such things were forbidden, or of having committed them, they being done unobserved, and through inadvertency; or were forgotten that they were done, or were done through error and mistake; these sins are what the apostle calls the errors of the people, their strayings…”

“And the Lord spake ... Israel - This formula is the commencement of a distinct section of the Law. Leviticus 4:2 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…”

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.

“through: Lev 5:15, Lev 5:17; Num 15:22-29; Deu 19:4; Sa1 14:27; Psa 19:12; Ti1 1:13; Heb 5:2, Heb 9:7 which ought: Lev 4:27; Gen 20:9; Jam 3:10 Leviticus 4:3”

“The Sin-Offerings. - The ritual prescribed for these differed, with regard to the animals sacrificed, the sprinkling of the blood, and the course adopted with the flesh, according to the position which the person presenting them happened to occupy in the kingdom of God. The classification of persons was as follows: (1) the anointed priest ( Lev 4:2-12); (2) the whole congregation of Israel ( Lev 5:13 -21); (3) the prince (vv. 22-26); (4) the common people (v. 27- Lev 5:13). In the case of the last, regard was also paid to their circumstances; so that the sin-offerings could be regulated according to the ability of the offerer, especially for the lighter forms of sin ( Lev 5:1-13).
