It is a third impressive fact, that after we include all the cases for which the sin-offering was provided, there still remain many sins for the forgiveness of which no provision was made. It was ordered elsewhere, for instance (Numb. xxxv. 31-33) that no satisfaction, should be taken for the life of a murderer. He might confess and bewail his sin, and be never so sorry, but there was no help for him; he must die the death. So was it also with blasphemy; so with adultery, and with many other crimes. This exclusion of so many cases from the merciful provision of the typical offering had a meaning. It was intended, not only to emphasise to the conscience the aggravated wickedness of such crimes, but also to develop in Israel the sense of need for a more adequate provision, a better sacrifice than any the Levitical law could offer; blood which should cleanse, not merely in a ceremonial and sacramental way, but really and effectively; and not only from some sins, but from all sins. The law of the sin-offering is introduced by phraseology different from that which is used in the case of the preceding offerings. In the case of each of these, the language used implies that the Israelites were familiar with the offering before its incorporation into the Levitical sacrificial system. The sin-offering, on the other hand, is introduced as a new thing. And such, indeed, it was. While, as we have seen, each of the offerings before ordered had been known and used, both by the Shemitic and the other nations, since long before the days of Moses, before this time there is no mention anywhere, in Scripture or out of it, of a sacrifice corresponding to the sin- or the guilt-offering. The significance of this fact is apparent so soon as we observe what was the distinctive conception of the sin-offering, as contrasted with the other offerings. Without question, it was the idea of expiation of guilt by the sacrifice of a substituted victim. This idea, as we have seen, was indeed not absent from the other bloody offerings; but in those its place was secondary and subordinate. In the ritual of the sin-offering, on the contrary, this idea was brought out into almost solitary prominence;--sin pardoned on the ground of expiation made through the presentation to God of the blood of an innocent victim.
