Leviticus 4:2-5

2“Speak to the children of Israel, saying: ‘If a person sins unintentionally against any of the commandments of the Lord in anything which ought not to be done, and does any of them,

3if the anointed priest sins, bringing guilt on the people, then let him offer to the Lord for his sin which he has sinned a young bull without blemish as a sin offering.

4He shall bring the bull to the door of the tabernacle of meeting before the Lord, lay his hand on the bull’s head, and kill the bull before the Lord.

5Then the anointed priest shall take some of the bull’s blood and bring it to the tabernacle of meeting.
