3. Mose 8:31

Induction of Aaron and His Sonsinto the Priestly Office - Leviticus 8-10 To the law of sacrifice there is appended first of all an account of the fulfilment of the divine command to sanctify Aaron and his sons as priests, which Moses had received upon the mount along with the laws concerning the erection of the sanctuary of the tabernacle (Ex 28 and 29). This command could not properly be carried out till after the appointment and regulation of the institution of sacrifice, because most of the laws of sacrifice had some bearing upon this act. The sanctification of the persons, whom God had called to be His priests, consisted in a solemn consecration of these persons to their office by investiture, anointing, and sacrifice (ch. 8), - their solemn entrance upon their office by sacrifices for themselves and the people (ch. 9), - the sanctification of their priesthood by the judgment of God upon the eldest sons of Aaron, when about to offer strange, fire-and certain instructions, occasioned by this occurrence, concerning the conduct of the priests in the performance of their service (ch. 10).

Moses, having done his part of the ceremony, now leaves Aaron and his sons to do theirs. I. They must boil the flesh of their peace-offering, and eat it in the court of the tabernacle, and what remained they must burn with fire, Lev 8:31, Lev 8:32. This signified their thankful consent to the consecration: when God gave Ezekiel his commission, he told him to eat the roll, Eze 3:1, Eze 3:2. II. They must not stir out of the court of the tabernacle for seven days, Lev 8:33. The priesthood being a good warfare, they must thus learn to endure hardness, and to disentangle themselves from the affairs of this life, Ti2 2:3, Ti2 2:4. Being consecrated to their service, they must give themselves wholly to it, and attend continually to this very thing. Thus Christ's apostles were appointed to wait for the promise of the Father, Act 1:4. During this time appointed for their consecration, they were daily to repeat the same sacrifices which were offered the first day, Lev 8:34. This shows the imperfection of the legal sacrifices, which, because they could not take away sin, were often repeated (Heb 10:1, Heb 10:2), but were here repeated seven times (a number of perfection), because they typified that one offering, which perfected for ever those that were sanctified. The work lasted seven days; for it was a kind of creation: and this time was appointed in honour of the sabbath, which, probably, was the last day of the seven, for which they were to prepare during the six days. Thus the time of our life, like the six days, must be our preparation for the perfection of our consecration to God in the everlasting sabbath: they attended day and night (Lev 8:35), and so constant should we be in our meditation on God's law, Psa 1:2. They attended to keep the charge of the Lord: we have ever…

8:31 The ordination offering was a variation of the peace offering (Exod 29:28). It was a meal (Lev 7:11-18, 28-34) shared between God (the parts burned on the altar) and the priests. The command to boil . . . and eat the ordination offering first appears in Exod 29:32.
