Leviticus 5:6, 9, 12

He must bring an offering to the LORD as a penalty for sin; it must be a female lamb or goat from the flock. The priest will perform the acts to remove that person’s sin so he will belong to the LORD.

He must sprinkle the blood from the sin offering on the side of the altar, and then he must pour the rest of the blood at the bottom of the altar; it is a sin offering.

He must bring the flour to the priest. The priest will take a handful of the flour as a memorial offering and burn it on the altar on top of the offerings made by fire to the LORD; it is a sin offering.
