And Aaron shall lay both his hands upon the head of the live goat, and confess over him all the iniquities of the children of Israel, and all their transgressions in all their sins, putting them {g} upon the head of the goat, and shall send him away by the hand of a fit man into the wilderness:

(g) In this goat is a true figure of Jesus Christ, who bears the sins of the people, Is 53:9.

Wesley's Notes

16:21 All the iniquities - He mentions iniquities, transgressions, and sins, to note sins of all sorts, and that a free and full confession was to be made, and that the smallest sins needed, and the greatest sins were not excluded from, the benefit of Christ's death here represented. On the head - Charging all their sins and the punishment due to them upon the goat, which tho' only a ceremony, yet being done according to God's appointment and manifestly pointing at Christ upon whom their iniquities and punishments were laid, Isa 53:5,6, it was available for this end. And hence the Heathens took their custom of selecting one beast or man, upon whom they laid all their imprecations and curses, and whom they killed as an expiatory sacrifice for their sins, and to prevent their ruin. A fit man - Heb. a man of time, that is, of years and discretion, who may be trusted with this work. Into the wilderness - Which signified the removal of their sins far away both from the people, and out of God's sight. And here the goat being neglected by all men, and exposed to many hazards from wild beasts, which were numerous there, might farther signify Christ's being forsaken both by God and by men, even by his own disciples, and the many dangers and sufferings he underwent. The Jews write, that this goat was carried to the mountain called Azazel, whence the goat is so called, Lev 16:10, and that there he was cast down headlong.

a fit...: Heb. a man of opportunity

Matthew Henry's Concise Commentary

16:15-34 Here are typified the two great gospel privileges, of the remission of sin, and access to God, both of which we owe to our Lord Jesus. See the expiation of guilt. Christ is both the Maker and the Matter of the atonement; for he is the Priest, the High Priest, that makes reconciliation for the sins of the people. And as Christ is the High Priest, so he is the Sacrifice with which atonement is made; for he is all in all in our reconciliation to God. Thus he was figured by the two goats. The slain goat was a type of Christ dying for our sins; the scape-goat a type of Christ rising again for our justification. The atonement is said to be completed by putting the sins of Israel upon the head of the goat, which was sent away into a wilderness, a land not inhabited; and the sending away of the goat represented the free and full remission of their sins. He shall bear upon him all their iniquities. Thus Christ, the Lamb of God, takes away the sin of the world, by taking it upon himself, Joh 1:29. The entrance into heaven, which Christ made for us, was typified by the high priest's entrance into the most holy place. See Heb 9:7. The high priest was to come out again; but our Lord Jesus ever lives, making intercession, and always appears in the presence of God for us. Here are typified the two great gospel duties of faith and repentance. By faith we put our hands upon the head of the offering; relying on Christ as the Lord our Righteousness, pleading his satisfaction, as that which alone is able to atone for our sins, and procure us a pardon. By repentance we afflict our souls; not only fasting for a time from the delights of the body, but inwardly sorrowing for sin, and living a life of self-denial, assuring ourselves, that if we confess our sins, God is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness. By the atonement we obtain rest for our souls, and all the glorious liberties of the children of God. Sinner, get the blood of Christ effectually applied to thy soul, or else thou canst never look God in the face with any comfort or acceptance. Take this blood of Christ, apply it by faith, and see how it atones with God.
