Leviticus 16:22

All their iniquities. The Israelites knew that they had sinned and come short of God’s expectation for them. But throughout this Day of Atonement they had had a visual demonstration of their complete separation from the sins they had confessed and been forgiven during the year that had now ended, and of God’s goodness in sparing their lives. They knew that they did not deserve the grace extended them. But by the shed blood of the atonement-day sacrifice the very record of their forgiven sins had been blotted from the sanctuary. Now as they watched the scapegoat depart they witnessed the last act in the drama — Satan, with all the sins he had instigated returned “upon his own head” (Ps. 7:16), going off to his doom.
