2. Mose 29:1

Consecration of Aaron and his Sons through the anointing of their persons and the offering of sacrifices, the directions for which form the subject of vv. 1-35. This can only be fully understood in connection with the sacrificial law contained in Lev 1-7. It will be more advisable therefore to defer the examination of this ceremony till we come to Lev 8, where the consecration itself is described. The same may also be said of the expiation and anointing of the altar, which are commanded in Exo 29:36 and Exo 29:37, and carried out in Lev 8:11.

Here is, I. The law concerning the consecration of Aaron and his sons to the priest's office, which was to be done with a great deal of ceremony and solemnity, that they themselves might be duly affected with the greatness of the work to which they were called, and that the people also might learn to magnify the office and none might dare to invade it. 1. The ceremonies wherewith it was to be done were very fully and particularly appointed, because nothing of this kind had been done before, and because it was to be a statute for ever that the high priest should be thus inaugurated. Now, (1.) The work to be done was the consecrating of the persons whom God had chosen to be priests, by which they devoted and gave up themselves to the service of God and God declared his acceptance of them; and the people were made to know that they glorified not themselves to be made priests, but were called of God, Heb 5:4, Heb 5:5. They were thus distinguished from common men, sequestered from common services, and set apart for God and an immediate attendance on him. Note, All that are to be employed for God are to be sanctified to him. The person must first be accepted, and then the performance. The Hebrew phrase for consecrating is filling the hand (Exo 29:9): Thou shalt fill the hand of Aaron and his sons, and the ram of consecration is the ram of fillings, Exo 29:22, Exo 29:26. The consecrating of them was the perfecting of them; Christ is said to be perfect or consecrated for evermore, Heb 7:28. Probably the phrase here is borrowed from the putting of the sacrifice into their hand, to be waved before the Lord, Exo 29:24. But it intimates, [1.] That ministers have their hands full; they have no time to trifle, so great, so copious, so constant is their work. [2.] That they must have…

29:1-37 Moses was required to consecrate (or sanctify) Aaron and his sons to serve the Lord. This emphasis on making the priests holy is found throughout the ceremonies (29:6, 21, 28, 29, 34, 36, 37). They were set apart not merely for service, but to serve a God whose nature is utterly different from that of fallen, sinful humans. The report of how these instructions were carried out is found in Lev 8. 29:1 with no defects: The same word is translated “blameless” and “perfect” in reference to human and divine behavior (e.g., Gen 17:1; Ps 18:30, 32). The sacrifice is representative of God’s own character and the character he seeks in humans.
