Which book describes the Day of Atonement?

The Day of Atonement is described in detail in the Book of Leviticus, specifically in Leviticus 16. This chapter outlines the rituals and practices that the Israelites were to follow in observance of this significant day, which plays a crucial role in the atonement for the sins of the people. The procedures include the selection of two goats, one to be sacrificed and the other, the scapegoat, to be sent into the wilderness, symbolically carrying away the sins of the people.

While Exodus, Numbers, and Deuteronomy contain important laws and events related to Israel's history and relationship with God, they do not provide the specific details regarding the Day of Atonement found in Leviticus. Thus, Leviticus is the book that specifically addresses this critical aspect of worship within the Israelite community. Understanding the content and context of Leviticus aids in grasping the theological significance of the Day of Atonement in the biblical framework.
