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). It is an heave-offering; under which is comprehended also the wave-offering; as plainly appears both from the context, and from the parity of reason, these offerings being of the same nature, and designed for the same purpose.

And it shall be Aaron's and his sons by a statute for ever from the children of Israel,.... That is, the shoulder, which seems particularly meant, though the breast also was theirs, which was at this time given to Moses, he being priest; and this was an everlasting statute and ordinance in all generations, as long as the priesthood of Aaron lasted, until the Messiah should come and put an end to it: and this the children of Israel were always to allow the priests; the shoulder, because Aaron bore their names before the Lord upon his shoulders, for a memorial; and the breast for a like reason, because he bore their names in the breastplate of judgment upon his heart, and their judgment also before the Lord continually, Exodus 28:12,

for it is an heave offering: it is lifted up to the Lord, and therefore is given to his priest:

and it shall be an heave offering from the children of Israel of the sacrifice of their peace offerings, even their heave offering unto the Lord: it being heaved up and given to the priest, it was reckoned an offering to the Lord, and was accepted by him as a peace offering; and it was an emblem of the lifting up of their hearts to God, and of the going up of the affections and desires of their souls to him, and of their serving and worshipping him in spirit and in truth, who is a spirit, and was their Father in heaven, to whom their eyes, hearts, and hands, were to be lifted up.

And it shall be Aaron's and his sons' by a statute for ever from the children of Israel: for it is an heave offering: and it shall be an heave offering from the children of Israel of the sacrifice of their {k} peace offerings, even their heave offering unto the LORD.

(k) Which were offerings of thanksgiving to God for his benefits.
