Leviticus 4:27–35

²⁷“Now if any of the common people^B sins unintentionally by violating one of the Lord’s commands, does what is prohibited, and incurs guilt, ²⁸or if someone informs him about the sin he has committed, then he is to bring an unblemished female goat as his offering for the sin that he has committed. 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 and apply it to the horns of the altar of burnt offering. He is to pour out the rest of its blood at the base of the altar. ³¹He is to remove all its fat just as the fat is removed from the fellowship sacrifice. The priest is to burn it on the altar as a pleasing aroma to the Lord. In this way the priest will make atonement on his behalf, and he will be forgiven.

³²“Or if the offering that he brings as a sin offering is a lamb,ⁿ he is to bring an unblemished female. ³³He 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. ³⁴Then the priest is to take some of the blood of the sin offering with his finger and apply it to the horns of the altar of burnt offering. He is to pour out the rest of its blood at the base of the altar. ³⁵He is to remove all its fat just as the fat of the lamb is removed from the fellowship sacrifice. The priest will burn it on the altar along with the food offerings to the Lord. In this way the priest will make atonement on his behalf for the sin he has committed, and he will be forgiven.
