15 "Take one of the rams, and Aaron and his sons shall lay their hands on its head. 16 Slaughter it and take the blood and splash it against the sides of the altar. 17 Cut the ram into pieces and wash the internal organs and the legs, putting them with the head and the other pieces. 18 Then burn the entire ram on the altar. It is a burnt offering to the Lord, a pleasing aroma, a food offering presented to the Lord.

Matthew Henry's Commentary on Exodus 29:15-18

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.
