With these modifications, it is plain that the sacrifice of consecration was essentially, not a guilt-offering, as some have supposed, but a peace-offering. It is true that a ram was enjoined as the victim instead of a lamb, but the correspondence here with the law of the guilt-offering is of no significance when we observe that rams were also enjoined or used for peace-offerings on other occasions of exceptional dignity and sanctity, as in the peace-offerings for the nation, mentioned in the following chapter, and the peace-offerings for the princes of the tribes (Numb. vii.). Unlike the guilt-offering, but after the manner of the other, the sacrifice was followed by a sacrificial feast. That participation in this was restricted to the priests, is sufficiently explained by the special relation of this sacrifice to their own consecration.
Before the sacrificial feast, however, one peculiar ceremony still remained. We read (ver. 30): "Moses took of the anointing oil, and of the blood (of the peace-offering) which was upon the altar, and sprinkled it upon Aaron, upon his garments, and upon his sons, and upon his sons' garments with him; and sanctified Aaron, his garments, and his sons, and his sons' garments with him."
This sprinkling signified that now, through the atoning blood which had been accepted before God upon the altar, and through the sanctifying Spirit of grace, which was symbolised by the anointing, thus inseparably associated each with the other, they had been brought into covenant relation with God regarding the office of the priesthood. That this their covenant relation to God concerned them, not merely as private persons, but in their official character, was intimated by the sprinkling, not only of their persons, but of the garments which were the insignia of their priestly office.
All this completed, now followed the sacrificial feast. We read that Moses now ordered Aaron and his sons (ver. 31): "Boil the flesh at the door of the tent of meeting: and there eat it and the bread that is in the basket of consecration, as I commanded, saying, Aaron and his sons shall eat it. And that which remaineth of the flesh and of the bread shall ye burn with fire."
This sacrificial feast most fitly marked the conclusion of the rites of consecration. Hereby it was signified, first, that by this solemn service they were now brought into a relation of peculiarly intimate fellowship with Jehovah, as the ministers of His house, to offer His offerings, and to be fed at His table. It was further signified, that strength for the duties of this office should be supplied to them by Him whom they were to serve, in that they were to be fed of His altar. And, finally, in that the ritual took the specific form of a thank-offering, was thereby expressed, as was fitting, their gratitude to God for the grace which had chosen them and set them apart to so holy and exalted service.
These consecration services were to be repeated for seven consecutive days, during which time they were not to leave the tent of meeting,--obviously, that by no chance they might contract any ceremonial defilement; so jealously must the sanctity of everything pertaining to the service be guarded.
The commandment was (vv. 33-35): "Ye shall not go out from the door of the tent of meeting seven days, until the days of your consecration be fulfilled: for he shall consecrate you seven days. As hath been done this day, so the Lord hath commanded to do, to make atonement for you. And at the door of the tent of meeting shall ye abide day and night seven days, and keep the charge of the Lord, that ye die not: for so I am commanded."
By the sevenfold repetition of the consecration ceremonies was expressed, in the most emphatic manner known to the Mosaic symbolism, the completeness of the consecration and qualification of Aaron and his sons for their office, and the fact also that, in virtue of this consecration, they had come into a special covenant relation with Jehovah concerning the priestly office.
