Leviticus 4:32-35

“ ‘If this person brings a lamb as his offering for sin, he must bring a female that has nothing wrong with it. He must put his hand on the animal’s head and kill it as a sin offering in the place where the whole burnt offering is killed. The priest must take some of the blood from the sin offering on his finger and put it on the corners of the altar of burnt offering. He must pour out the rest of the lamb’s blood at the bottom of the altar. Then the priest must remove all the lamb’s fat in the same way that the lamb’s fat is removed from the fellowship offerings. He must burn the pieces on the altar on top of the offerings made by fire for the LORD. In this way the priest will remove that person’s sins so he will belong to the LORD, and the LORD will forgive him.
