Leviticus 16 is a chapter that focuses on the Day of Atonement, a day of repentance and cleansing for the Israelites. It begins by outlining the instructions for the High Priest, who is to make atonement for the people of Israel. He is to take two goats, one for a sin offering and one for a burnt offering, and to cast lots for them. The goat chosen for the sin offering is to be sacrificed, and its blood is to be used to make atonement for the people. The other goat is to be sent away into the wilderness, symbolizing the removal of the people's sins.
The chapter then goes on to describe the ritual of the Day of Atonement. The High Priest is to enter the Most Holy Place and make atonement for himself and for the people. He is to sprinkle the blood of the sin offering on the mercy seat and on the altar of incense. He is also to burn incense and offer a bull as a sin offering.
The chapter ends with a reminder that the Day of Atonement is to be observed every year, and that it is a day of solemn rest. It is a day of repentance and cleansing, and a reminder of the need for the people to turn away from their sins and seek God's forgiveness.
