EXPOSITORY (ENGLISH BIBLE)
29:1-37 Aaron and his sons were to be set apart for the priest's office, with ceremony and solemnity. Our Lord Jesus is the great High Priest of our profession, called of God to be so; anointed with the Spirit, whence he is called Messiah, the Christ; clothed with glory and beauty; sanctified by his own blood; made perfect, or consecrated through sufferings, Heb 2:10. All believers are spiritual priests, to offer spiritual sacrifices,
Door of the tabernacle - Entrance of the tent. See Leviticus 8:3
10-22. And thou shalt cause a bullock to be brought before the tabernacle—This part of the ceremonial consisted of three sacrifices: (1) The sacrifice of a bullock, as a sin offering; and in rendering it, the priest was directed to put his hand upon the head of his sacrifice, expressing by that act a consciousness of personal guilt, and a wish that it might be accepted as a vicarious satisfaction. (2) The sacrifice of a ram as a burnt offering (Ex 29:15-18). The ram was to be wholly burnt, in token of the priest's dedication of himself to God and His service. The sin offering was first to be presented, and then the burnt offering; for until guilt be removed, no acceptable service can be performed. (3) There was to be a peace offering, called "the ram of consecration" (Ex 29:19-22). And there was a marked peculiarity in the manner in which this other ram was to be disposed of. The former was for the glory of God—this was for the comfort of the priest himself; and as a sign of a mutual covenant being ratified, the blood of the sacrifice was divided—part sprinkled on the altar round about, and part upon the persons and garments of the priests. Nay, the blood was, by a singular act, directed to be put upon the extremities of the body, thereby signifying that the benefits of the atonement would be applied to the whole nature of man. Moreover, the flesh of this sacrifice was to be divided, as it were, between God and the priest—part of it to be put into his hand to be waved up and down, in token of its being offered to God, and then it was to be burnt upon the altar; the other part was to be eaten by the priests at the door of the tabernacle—that feast being a symbol of communion or fellowship with God. These ceremonies, performed in the order described, showed the qualifications necessary for the priests. (See Heb 7:26, 27; 10:14).
Moses, who though no priest, yet for this time and occasion was called by God to this work.
And thou shalt kill the bullock before the Lord,.... That is, Moses is ordered to do it, who now officiated as a priest, "pro tempore", Aaron and his sons not being yet completely invested with that office, or thoroughly consecrated to it; of which consecration this sacrifice was a part, and therefore could not with propriety be concerned in killing their own sacrifice; for that purpose, Moses therefore did it, and he did it "before the Lord"; Jehovah the Son gave him those orders to do it before Jehovah the Father, in his presence, as an offering to him, and for his acceptance. And the ark, as Aben Ezra observes, was in the middle westward, and right against it was the altar of incense, and opposite that the altar of burnt offering:
by the door of the tabernacle of the congregation; that is, as Jarchi interprets it, in the court of the tabernacle before the door; not by the door by which they entered in to the court of the tabernacle; but in the court before the door that leads in to the holy at some distance from which stood the altar of burnt offering, where this bullock was slain and sacrificed: all this may denote the public manner in which Christ, the antitype, suffered in the presence of the Lord, with his knowledge and will, and before the people of Israel. And thou shalt kill the bullock before the LORD, by the door of the tabernacle of the congregation.
