19 "Then you shall take the other ram , and Aaron and his sons shall lay their hands on the head of the ram . 20 "You shall slaughter the ram , and take some of its blood and put it on the lobe of Aaron's right ear and on the lobes of his sons' right ears and on the thumbs of their right hands and on the big toes of their right feet , and sprinkle the rest of the blood around on the altar . 21 "Then you shall take some of the blood that is on the altar and some of the anointing oil , and sprinkle it on Aaron and on his garments and on his sons and on his sons' garments with him; so he and his garments shall be consecrated , as well as his sons and his sons' garments with him. 22 "You shall also take the fat from the ram and the fat tail , and the fat that covers the entrails and the lobe of the liver , and the two kidneys and the fat that is on them and the right thigh (for it is a ram of ordination ),

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.
