And thus shall thou do unto Aaron, and to his sons,.... For their consecration, washing, clothing, anointing them, sprinkling blood upon them and their garments, and offering sacrifice for them:
according to all things which I have commanded thee; no one thing was to be omitted, and we find they were carefully and punctually observed, Leviticus 8:1.
seven days shalt thou consecrate them: so long the rites and ceremonies of the consecration were to be performing, that they might be thoroughly used to the putting on of their garments, and the offering of sacrifices as they saw performed by Moses; and in all respects be fitted for the discharge of their office: the Jewish writers generally say that seven days were appointed, that a sabbath might pass over them.
seven days shalt thou consecrate them--The renewal of these ceremonies on the return of every day in the seven, with the intervention of a Sabbath, was a wise preparatory arrangement, in order to afford a sufficient interval for calm and devout reflection (Hebrews 9:1; Hebrews 10:1).
Seven days shalt thou consecrate them - Though all the ceremonies were performed on the first day, yet, they were not to look upon their consecration as compleated till the seven days end, which put a solemnity upon their admission, and a distance between this and their former state, and obliged them to enter upon their work with a pause, giving them time to consider the weight of it. This was to be observed in after ages: he that was to succeed Aaron in the high priesthood, must put on the holy garments seven days together, in token of a deliberate advance into his office, and that one sabbath might pass over him, in his consecration. Every day of the seven, in this first consecration, a bullock was to be offered for a sin - offering, which was to intimate, That though atonement was made, yet they must still keep up a penitent sense of sin, and often repeat the confession of it. That those sacrifices which were thus offered day by day, could not make the comers there unto perfect, for then they would have ceased to be offered; Hebrews 10:1-2. They must therefore expect the bringing in of a better hope. Now this consecration of the priests was a shadow of good things to come. Our Lord Jesus is the great high priest of our profession, called of God to be so consecrated for evermore, anointed with the Spirit above his fellows, whence he is called Messiah, the Christ; clothed with the holy garments, even with glory and beauty; sanctified by his own blood, not that of bullocks and rams. All believers are spiritual priests, to offer spiritual sacrifices, 1-Peter 2:5, washed in the blood of Christ, and so made to our God priests, Revelation 1:5-6. They also are clothed with the beauty of holiness, and have received the anointing, 1-John 2:27. His blood sprinkled upon the conscience, purgeth it from dead works, that they may, as priests, serve the living God. The Spirit of God is called the finger of God (Luke 11:20, compared with Matthew 12:28,) and by him the merit of Christ is effectually applied to our souls, as here Moses with his finger was to put the blood upon Aaron. It is likewise intimated that gospel ministers are to be solemnly set apart to the work of the ministry with great deliberation and seriousness, both in the ordainers, and in the ordained, as those that are employed in a great work, and intrusted with a great charge.
