Leviticus 4:27-31
27 “‘If a member of the community sins unintentionally and does what is forbidden in any of the Lord’s commands, he is guilty.
28 When he is made aware of the sin he committed, he must bring as his offering for the sin he committed a female goat without defect.
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 the blood with his finger and 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 He shall remove all the fat, just as the fat is removed from the fellowship offering, and the priest shall burn it on the altar as an aroma pleasing to the Lord. In this way the priest will make atonement for him, and he will be forgiven.
