Leviticus 4:12-15

12the entire bull—he is to carry outside the camp to a clean place, where the fat ashes are poured out, and burn it over wood in the fire. It is to be burned on top of the place of pouring fat ashes.

13“Now if the whole congregation of Israel sins, but the deed is hidden from the eyes of the community, yet they have done one of Adonai’s mitzvot that are not to be done, then they are guilty.

14When the sin that they committed becomes known, then the community is to offer a young bull for a sin offering, and bring it before the Tent of Meeting.

15The elders of the congregation are to lay their hands on the head of the bull before Adonai, and the bull is to be slaughtered before Adonai.
