Leviticus 4:29

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.

27 And if one of the common people sins unintentionally and does what is prohibited by any of the LORD’s commandments, he incurs guilt.

28 When he becomes aware of the sin he has committed, he must bring an unblemished female goat as his offering for that sin.

29 He is to lay his hand on the head of the sin offering and slaughter it at the place of the burnt offering.

30 Then the priest is to take some of its blood 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.

31 Then he is to remove all the fat, just as it is removed from the peace offering, and the priest is to burn it on the altar as a pleasing aroma to the LORD. In this way the priest will make atonement for him, and he will be forgiven.

32 If, however, he brings a lamb as a sin offering, he must bring an unblemished female.

33 And he is to lay his hand on the head of the sin offering and slaughter it as a sin offering at the place where the burnt offering is slaughtered.
