Leviticus 4:12-15

12to a clean  place outside the camp where the ashes are dumped. He will burn it there on a wood fire.

13“If the whole congregation of Israel unintentionally does something wrong, without the assembly being aware of it, if they do even one thing that is forbidden by any of the Lord’s commands, they will be guilty.

14When the wrong they have done becomes known, the congregation must sacrifice a bull as an offering for sin. They must bring it in front of the tent of meeting.

15The leaders of the congregation will place their hands on the bull’s head in the Lord’s presence. One of them will slaughter it in the Lord’s presence.
