11 You shall kill the bull before Yahweh, at the door of the Tent of Meeting. 12 You shall take of the blood of the bull, and put it on the horns of the altar with your finger; and you shall pour out all the blood at the base of the altar. 13 You shall take all the fat that covers the innards, the cover of the liver, the two kidneys, and the fat that is on them, and burn them on the altar. 14 But the flesh of the bull, and its skin, and its dung, you shall burn with fire outside of 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.
