What does the Bible say about the Day of Atonement?

The Day of Atonement, as outlined in Leviticus 16, was a significant annual event for the children of Israel, marking the day when the high priest, Aaron, would enter the holy place to make atonement for the sins of the people. This day symbolized God's provision for reconciliation through sacrificial offerings. The rituals performed were not mere traditions; they held profound significance as foreshadowing the ultimate atonement made by Jesus Christ, who, as the true high priest, would offer Himself as the final sacrifice for sin. The entire chapter details the steps Aaron had to undertake, illustrating the seriousness of sin and the holiness of God, which required a perfect offering for the cleansing of His people.
