Leviticus 4:22

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.

21 Then he is to take the bull outside the camp and burn it, just as he burned the first bull. It is the sin offering for the assembly.

22 When a leader sins unintentionally and does what is prohibited by any of the commandments of the LORD his God, he incurs guilt.

23 When he becomes aware of the sin he has committed, he must bring an unblemished male goat as his offering.

24 He is to lay his hand on the head of the goat and slaughter it at the place where the burnt offering is slaughtered before the LORD. It is a sin offering.

25 Then the priest is to take some of the blood of the sin offering with his finger, put it on the horns of the altar of burnt offering, and pour out the rest of the blood at the base of the altar.

26 He must burn all its fat on the altar, like the fat of the peace offerings; thus the priest will make atonement for that man’s sin, and he will be forgiven.
