Leviticus 4
2 Ref Say to the children of Israel: These are the offerings of anyone who does wrong through error, doing any of the things which by the Lord's order are not to be done:
3 Ref If the chief priest by doing wrong becomes a cause of sin to the people, then let him give to the Lord for the sin which he has done, an ox, without any mark, for a sin-offering.
4 Ref And he is to take the ox to the door of the Tent of meeting before the Lord; and put his hand on its head and put it to death before the Lord.
