The bullock was immediately slain at the door of “the tent of meeting”; and to show that the shedding of his blood was an essential part of the rite, part of it was put with the finger on the horns of the altar, and the remainder was poured out at the base. Only then might the fat and the kidney be burned upon the altar; but it is never said of any sin-offering, as presently of the burnt-offering and the peace-offerings, that it is “a sweet savour before Jehovah” (vers. 18, 25)—a phrase which is only once extended to a trespass-offering for a purely unconscious lapse (Lev. iv. 31). The sin-offering is, at the best, a deplorable necessity. And therefore the notion of a gift, welcome to Jehovah, is carefully shut out: no portion of such an offering may go to maintain the priests: all must be burned “with fire without the camp; it is a sin-offering” (ver. 14). Rightly does the Epistle to the Hebrews emphasize this fact: “The bodies of those beasts whose blood is brought into the Holy Place ... as an offering for sin” are burned without the camp. The bodies of other sacrifices were not reckoned unfit for food.[40] And so there is a striking example of humility, as well as an instructive coincidence, in the fact that Jesus suffered without the gate, being the true Sin-offering, “that He might sanctify the people through His own blood” (Heb. xiii. 11, 12). Thus, by sacrifice for sin, the priest is rendered fit to offer up to God the symbol of a devoted life. Again, therefore, the hands of Aaron and his sons are laid upon the head of the ram, because they come to offer what represents themselves in another sense than that of expiation—a sweet savour now, an offering made by fire unto Jehovah (ver. 18). And to show that it is perfectly acceptable to Him, the whole ram shall be burnt upon the altar, and not now without the camp: “it is a burnt-offering unto the Lord.” Such is the appointed way of God with man—first expiation, then devotion.
