“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 upon the head of the goat, and shall send him away by the hand of a fit man into the wilderness:”
King James Version (KJV)
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.
