(21) Take of the blood . . . and of the anointing oil.—The twofold sprinkling, with blood and with oil, denoted the necessity of a twofold holiness—that of justification by the atoning blood of Christ, and that of sanctification by the outpouring of the Holy Spirit. The anointing which is here spoken of seems to have been the only anointing received by the sons of Aaron. (See Leviticus 8:30.)

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). No text from Poole on this verse.

And thou shalt take of the blood that is upon the altar,.... Not that which was sprinkled upon it, which could not be gathered up in such quantities as to be sprinkled again; but which was in a basin on it, having been received into it when the ram was slain:

and of the anointing oil; hereafter to be made, and with which Aaron was anointed as soon as he had his garments on; and this is a different anointing from that that was poured on his head; this was sprinkled on his garments, as follows:

and sprinkle it upon Aaron; both the blood and the oil:

and upon his garments; the note of Aben Ezra is, under the garments of Aaron, and on his garments, as if they were sprinkled within and without:

and upon his sons, and upon the garments of his sons with him; at his first unction his sons do not seem to have been anointed at all, but now they and their garments are sprinkled both with blood and oil; denoting both the justification of the priests of the Lord by the blood of Christ, and the sanctification of them by the Spirit, and the need that both their persons and their actions stand in of cleansing by them both:

and he shall be hallowed, and his garments, and his sons, and his sons' garments with him: all should be holy in a ceremonial sense, and devoted to holy uses and services; see Psalm 45:8.

And thou shalt take of the blood that is {f} upon the altar, and of the anointing oil, and sprinkle it upon Aaron, and upon his garments, and upon his sons, and upon the garments of his sons with him: and he shall be hallowed, and his garments, and his sons, and his sons' garments with him.

(f) With which the Altar must be sprinkled.
