By this sin-offering, not only Aaron and his sons were cleansed, but we read that hereby atonement was also made "for the altar;" a mysterious type, reminding us that, in some way which we cannot as yet fully understand, sin has affected the whole universe: in such a sense, that not only for man himself who has sinned, is propitiation required, but, in some sense, even for the earth itself, with the heavens. That in expounding the meaning of this part of the ritual we do not go beyond the Scripture is plain from such passages as Heb. ix. 23, where it is expressly said that even as the tabernacle and the things in it were cleansed with the blood of the bullock, so was necessary that, not merely man, but "the heavenly things themselves," of which the tabernacle and its belongings were the "copies," should be cleansed with better sacrifices than these, even the offering of Christ's own blood. So also we read in Col. i. 20, before cited, that through Christ, even through the blood of His cross, not merely persons, "but all _things_, whether things on the earth, or things in the heavens," should be reconciled unto God. Mysterious words these, no doubt; but words which teach us at least so much as this, how profound and far-reaching is the mischief which sin has wrought, even our sin. Not merely the sinning man must be cleansed with blood before he can be made a priest unto God, but even nature, "made subject to vanity" (Rom. viii. 20), for man's sin, needs the reconciling blood before redeemed man can exercise his priesthood unto God in the heavenly places. Evidently we have here an estimate of the evil of sin which is incomparably higher than that which is commonly current among men; and we shall do well to conform our estimate to that of God, who required atonement to be made even for the earthen altar, to sanctify it. Reconciliation being made by the sin-offering, next in order came the burnt-offering, symbolic, as we have seen, of the full consecration of the person of the offerer to God; in this case of the full consecration of Aaron and his sons to the service of God in the priesthood. The ritual was according to the usual law, and requires no further exposition.
