Leviticus 4:2-3

Speak to the people of Israel, saying a If anyone sins unintentionally
Or by mistake; so throughout Leviticus
in any of the  Lord’s commandments c about things not to be done, and does any one of them,
if it is the anointed priest who d sins, thus bringing guilt on the people, then he shall offer for the sin that he has committed e a bull from the herd without blemish to the  Lord for a sin offering.
