Leviticus 4:16

12 all the rest of the bull—he must take outside the camp to a ceremonially clean place where the ashes are poured out, and there he must burn it on a wood fire on the ash heap.

13 Now if the whole congregation of Israel strays unintentionally and the matter escapes the notice of the assembly so that they violate any of the LORD’s commandments and incur guilt by doing what is forbidden,

14 when they become aware of the sin they have committed, then the assembly must bring a young bull as a sin offering and present it before the Tent of Meeting.

15 The elders of the congregation are to lay their hands on the bull’s head before the LORD, and it shall be slaughtered before the LORD.

16 Then the anointed priest is to bring some of the bull’s blood into the Tent of Meeting,

17 and he is to dip his finger in the blood and sprinkle it seven times before the LORD in front of the veil.

18 He is also to put some of the blood on the horns of the altar that is before the LORD in the Tent of Meeting, and he must pour out the rest of the blood at the base of the altar of burnt offering at the entrance to the Tent of Meeting.

19 And he is to remove all the fat from it and burn it on the altar.

20 He shall offer this bull just as he did the bull for the sin offering; in this way the priest will make atonement on their behalf, and they will be forgiven.
