Leviticus 5:6, 9, 12

and he shall bring his trespass-offering unto Jehovah for his sin which he hath sinned, a female from the flock, a lamb or a goat, for a sin-offering; and the priest shall make atonement for him as concerning his sin.

and he shall sprinkle of the blood of the sin-offering upon the side of the altar; and the rest of the blood shall be drained out at the base of the altar: it is a sin-offering.

And he shall bring it to the priest, and the priest shall take his handful of it as the memorial thereof, and burn it on the altar, upon the offerings of Jehovah made by fire: it is a sin-offering.
