Leviticus 4:2-5

2“Tell the Israelites: When someone sins unintentionally against any of the Lord’s commands and does anything prohibited by them —

3“If the anointed priest sins, bringing guilt on the people, he is to present to the Lord a young, unblemished bull as a sin offering for the sin he has committed.

4He is to bring the bull to the entrance to the tent of meeting before the Lord, lay his hand on the bull’s head, and slaughter it before the Lord.

5The anointed priest will then take some of the bull’s blood and bring it into the tent of meeting.
