11 'And thou hast slaughtered the bullock before Jehovah, at the opening of the tent of meeting, 12 and hast taken of the blood of the bullock, and hast put 'it' on the horns of the altar with thy finger, and all the blood thou dost pour out at the foundation of the altar; 13 and thou hast taken all the fat which is covering the inwards, and the redundance on the liver, and the two kidneys, and the fat which 'is' on them, and hast made perfume on the altar; 14 and the flesh of the bullock, and his skin, and his dung, thou dost burn with fire at the outside of the camp; it 'is' a sin-offering.
Matthew Henry's Commentary on Exodus 29:11-14
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.
