Leviticus 4:2-4

2“Say to the Israelites: ‘When anyone sins unintentionally and does what is forbidden in any of the Lord’s commands— 3“ ‘If the anointed priest sins, bringing guilt on the people, he must bring to the Lord a young bull without defect as a sin offering for the sin he has committed. 4He is to present the bull at the entrance to the tent of meeting before the Lord. He is to lay his hand on its head and slaughter it there before the Lord.
