10 "Bring the young bull to the entrance of the Tabernacle, where Aaron and his sons will lay their hands on its head. 11 Then slaughter the bull in the Lord 's presence at the entrance of the Tabernacle. 12 Put some of its blood on the horns of the altar with your finger, and pour out the rest at the base of the altar. 13 Take all the fat around the internal organs, the long lobe of the liver, and the two kidneys and the fat around them, and burn it all on the altar. 14 Then take the rest of the bull, including its hide, meat, and dung, and burn it outside the camp as 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.
