11 And thou shalt kill the bullock before Jehovah, at the door of the tent of meeting. 12 And thou shalt take of the blood of the bullock, and put it upon the horns of the altar with thy finger; and thou shalt pour out all the blood at the base of the altar. 13 And thou shalt take all the fat that covereth the inwards, and the caul upon the liver, and the two kidneys, and the fat that is upon them, and burn them upon the altar. 14 But the flesh of the bullock, and its skin, and it dung, shalt thou burn with fire without the camp: it is a sin-offering.

Commentary on Exodus 29:1-37
(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.
