The offering on the Day of Atonement is unique in that it is a singular offering in two parts, each goat representing a separate aspect of Christ's sacrifice. In Part Three, David Grabbe explains why the goat of departure cannot be connected to the binding of Satan (Revelation 20:1-3), as well as how Hebrews 9 and 10 clarify the Atonement ritual's meaning through the complete—and completed—sacrifice of Christ.
In the pivotal ritual on the Day of Atonement, two goats play significant and separate roles to represent specific divine purposes within the process of salvation. As David Grabbe explains, understanding the role of the live goat hinges on recognizing whose sins are in view, as well as who is actually responsible for sin.
David Grabbe, reiterating that the two goats of Leviticus 16 make a composite sacrifice for sin, reminds us that every sacrifice in the Levitical sacrificial system was an unblemished animal. The first goat in Leviticus 16 was to satisfy God's demand for justice with a covering of blood. The second goat symbolizes the removal of sin, expunging its memory from the camp of Israel and from God's mind, transferring it into oblivion, symbolized by an uninhabited wasteland- as far as East is from the West. The live goat was a substitutionary sacrifice for the whole nation. The goat of departure bore the sins of the entire people, carrying the sins out of sight and out of mind. Christ, as a substitutionary sacrifice, bore the sins of all of humanity, carrying them out of sight. Satan, because his sins are numerous, cannot be a substitutionary sacrifice for anyone. The sins have been blotted out, totally erased from the mind of God. Sin is disannulled, neutralized, cast off, and obliterated, removed from consciousness and conscience. Satan has no role in this process.
