36 Also every day you shall offer a bull as a sin offering for atonement. Also you shall offer a sin offering for the altar, when you make atonement for it, and shall anoint it, to consecrate it.

Matthew Henry's Commentary on Exodus 29:36

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.
