Leviticus 4:2-5

2‘Say to Israel's people, “A man may sin, when he did not really want to sin against the Lord. This is what that person must do.

3The man may be a priest that you have anointed. If that is true, his sins will cause the people to sin. He must bring a young bull as a gift to the Lord.

4The priest must bring the young bull to the door of the Lord's Tent of Meeting. He must put his hand on the animal's head. And then he must kill it in front of the Lord.

5The priest that you have anointed must carry some of the blood into the Tent of Meeting.
