20 and 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 the right ears of his sons, and on the thumbs of their right hands, and on the big toes of their right feet, and dash the rest of the blood against all sides of the altar.
Matthew Henry's Commentary on Exodus 29:20
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.
