What does the Bible say about the Day of Atonement?

The Day of Atonement, outlined in Leviticus 16, is a significant event in the Jewish sacrificial system where the high priest makes atonement for the sins of the people. It serves as a yearly reminder of the necessity of blood sacrifice for reconciliation with God. On this day, the high priest would enter the Holy of Holies, making a sin offering for himself and the people. This ceremony foreshadows the ultimate sacrifice of Jesus Christ, our Great High Priest, who offered Himself once for all, thus fulfilling the requirements of the law and providing complete atonement for sin. It signifies how God predetermined this means of atonement and how it brings perfect peace and cleansing to His people, reaffirmed by Christ’s declaration, 'It is finished' at the cross.
