Leviticus 16:21

Aaron shall lay both his hands upon the head, etc. - What this imposition of hands meant see in the notes on Exodus 29:10 (note), and Leviticus 1:4 (note).

And confess over him all the iniquities - transgressions - sins - The three terms used here, Iniquities, עונת avonoth, from עוה avah, to pervert, distort, or turn aside; Transgressions, פשעים peshaim, from פשע pasha, to transgress, to rebel; and Sins, חטאת chattaoth, from חטא chata, to miss the mark, are supposed by the Jews to comprise every thing that implies a breach of the Divine law, or an offense against God. See Clarke's note on Genesis 12:13. Maimonides gives us the confession in the following words: -

"O Lord, thy people, the house of Israel, have sinned and done iniquity, and trespassed before thee. O Lord, make atonement now for the iniquities and transgressions and sins that thy people, the house of Israel, have sinned and transgressed against thee; as it is written in the law of Moses thy servant, saying: That in this day he shall make atonement for you, to cleanse you from all your sins before the Lord, and ye shall be clean." - See the Mishna, vol. ii., p. 329. When this confession was finished, the goat was sent by a proper hand to the wilderness, and there let loose; and nothing farther was ever heard of it. Did not all this signify that Christ has so carried and borne away our sins, that against them who receive him as the only true atoning sacrifice they should never more be brought to remembrance? On the head of the scape-goat, a piece of scarlet cloth was tied, and the tradition of the Jews states that if God accepted the sacrifice, the scarlet cloth turned white while the goat was led to the desert; but if God had not accepted this expiation, the redness continued, and the rest of the year was spent in mourning. From the foundation of the Church of God it was ever believed by his followers, that there were certain infallible tokens by which he discovered to genuine believers his acceptance of them and their services. This was sometimes done by a fire from heaven consuming the sacrifice; sometimes by an oracular communication to the priest or prophet; and at other times, according to the Jewish account, by changing the fillet or cloth on the head of the scape-goat from scarlet to white: but most commonly, and especially under the Gospel dispensation, he gives this assurance to true believers by the testimony of his Spirit in their consciences, that he has forgiven their iniquities, transgressions, and sins, for his sake who has carried their griefs, and borne their sorrows.

Confess over him - The form of confession used on this occasion in later times was: "O Lord, Thy people, the house of Israel, have transgressed, they have rebelled, they have sinned before Thee. I beseech Thee now absolve their transgressions, their rebellion, and their sin that they have sinned against Thee, as it is written in the law of Moses Thy servant, that on this day he shall make atonement for you to cleanse you from all your sins, and ye shall be clean."

A fit man - literally, a timely man, or a man at hand. Tradition says that the man was appointed for this work the year before.

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, Isaiah 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, Leviticus 16:10 , and that there he was cast down headlong.
