Leviticus 4:24-30

24He 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. 25Then 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. 26He 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.

27And if one of the common people sins unintentionally and does what is prohibited by any of the LORD’s commandments, he incurs guilt. 28When he becomes aware of the sin he has committed, he must bring an unblemished female goat as his offering for that sin. 29He is to lay his hand on the head of the sin offering and slaughter it at the place of the burnt offering. 30Then 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.
