(10) Thou shalt cause a bullock to be brought.—Rather, the bullock: i.e., the bullock mentioned in Exodus 29:1, which was to be kept in readiness for the consecration sacrifice.

Aaron and his sons shall put their hands upon the head of the bullock.—By this symbolical action, which was commanded in the case of every sin offering (Leviticus 4:4; Leviticus 4:15; Leviticus 4:24; Leviticus 4:29; Leviticus 4:33; Leviticus 16:21, &c.), the offerer identified himself with the animal, and transferred to it the guilt of his own sins and imperfections. The animal thereby became accursed, and its death paid the penalty due to the sins laid upon it, and set free those who had committed them. Similarly, Christ, our sin offering, was “made a curse for us” (Galatians 3:13).

Exodus 29:10. There must be a sin-offering to make atonement for them. The law made them priests that had infirmity; and therefore they must first offer for their own sins, before they could make atonement for the people, Hebrews 7:27-28. They were to put their hand on the head of their sacrifice; confessing that they deserved to die for their own sins, and desiring that the killing of the beast might be accepted as a vicarious satisfaction. It was used as other sin-offerings were; only, whereas the flesh of other sin-offerings was eaten by the priests, in token of the priests taking away the sins of the people, this was appointed to be all burned without the camp, to signify the imperfection of the legal dispensation, for the sins of the priests themselves could not be taken away by those sacrifices, but they must expect a better high-priest, and a better sacrifice.

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). To signify that they offered it for themselves and for their own sins, which the offerer performing this rite was to confess, Leviticus 16:21, that they acknowledged themselves to deserve that death which was inflicted upon this innocent creature for their sakes, and to testify their faith in the future sacrifice of Christ, upon whom their sins were to be laid, and by whose blood they were expiated, and that they humbly begged God’s mercy in pardoning their sins, and accepting them to and in their holy office.

And thou shalt cause a bullock to be brought before the tabernacle of the congregation,.... The same, or of the same kind he was ordered to take, Exodus 29:1, and here the place is expressed where it was to be taken, and what was to be done with it:

and Aaron and his sons shall put their hands upon the head of the bullock; not Aaron first alone, and then his sons, as some have thought, Aben Ezra makes mention of; but, as he says, both together, not one before another; declaring it to be their sacrifice, a vicarious one, one in their room and stead, signifying that they deserved to die as that creature would; and by this act putting, as it were, their sins and transgressions upon it, see Leviticus 16:21 and which was an emblem of the imputation of sin to Christ, and laying upon him the iniquities of us all.

And thou shalt cause a bullock to be brought before the tabernacle of the congregation: and Aaron and his sons shall {c} put their hands upon the head of the bullock.

(c) Signifying that the sacrifice was also offered for them, and that they approved it.
