Leviticus 5:6, 9
and he must bring his guilt offering to the LORD for the sin he has committed: a female lamb or goat from the flock as a sin offering. And the priest will make atonement for him concerning his sin. / then he is to sprinkle some of the blood of the sin offering on the side of the altar, while the rest of the blood is drained out at the base of the altar. It is a sin offering.
