10 And thou shalt present the bullock before the tent of meeting; and Aaron and his sons shall lay their hands upon the head of the bullock; 11 and thou shalt slaughter the bullock before Jehovah, at the entrance of the tent of meeting; 12 and thou shalt take of the blood of the bullock, and put it on the horns of the altar with thy finger, and shalt pour all the blood at the bottom of the altar. 13 And thou shalt take all the fat that covereth the inwards, and the net of the liver, and the two kidneys, and the fat that is upon them, and burn them upon the altar. 14 And the flesh of the bullock, and its skin, and its dung, shalt thou burn with fire outside the camp: it is a sin-offering.

(Read Exodus 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, Matthew 12:28,) and by him the merit of Christ is applied to our souls. This consecration signifies the admission of a sinner into the spiritual priesthood, to offer spiritual sacrifices, acceptable to God through Jesus Christ.
