Leviticus 4:27-31

27“If a common person unintentionally does something wrong—even one thing forbidden by the Lord’s commands—he will be guilty.

28When he is told about what he has done wrong, he must bring a female goat that has no defects as his offering for what he has done wrong.

29He will place his hand on the animal’s head and slaughter it where animals for burnt offerings are slaughtered.

30The priest will take some of the blood with his finger and put it on the horns of the altar for burnt offerings. He will pour the rest of the blood at the bottom of the altar.

31He will remove all the fat the same way it is removed from the fellowship offering. The priest will burn it on the altar for a soothing aroma to the Lord. So the priest will make peace with the Lord for that person, and that person will be forgiven.
