Leviticus 4:2-5

2“Speak to Bnei-Yisrael, saying: If anyone sins unintentionally in any of Adonai’s mitzvot that are not to be done, and commits any one of them

3—or if the anointed kohen sins so as to bring guilt on the people—then let him offer for his sin which he has committed, a young bull without blemish to Adonai for a sin offering.

4He is to bring the bull to the entrance of the Tent of Meeting before Adonai, lay his hand on the head of the bull, and slaughter it before Adonai.

5The anointed kohen shall take some of the blood of the bull, and bring it to the Tent of Meeting.
