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,The "waving" was the more solemn process of the two: it was a movement several times repeated, while "heaving" was simply a "lifting up" once.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). For so long the solemnity of the consecration lasted, Exodus 29:35.

In the holy place; both that strictly so called, and in the most holy place; for as none could go into the most holy place except the high priest, so there were some things to be done in the holy place which none but he could do. See Leviticus 4:7,8.

And that son that is priest in his stead,.... The Targum of Jonathan is,"who shall rise after him of his sons, not of the Levites;''for the high priest was to be of the family of Aaron, a descendant of his; it was not enough that he was of the tribe of Levi, but he must descend from Aaron, either in the line of Eleazar or of Ithamar:

shall put them on seven days; the next successor was to wear the garments seven days running:

when he cometh into the tabernacle of the congregation to minister in the holy place; to offer sacrifice in the court of the tabernacle, on the altar of burnt offering, and to offer incense on the altar of incense, and to trim the lamps of the candlestick, and to put the shewbread on the table.

And that son that is priest in his stead shall put them on seven days, when he cometh into the tabernacle of the congregation to minister in the holy place.
