Leviticus 5:9-10

EJ2000(i) 9 and he shall sprinkle of the blood of the sin upon the side of the altar; and the rest of the blood shall be wrung out at the bottom of the altar; it is sin. 10 And he shall offer the second for a burnt offering, according to the ordinance; and thus shall the priest reconcile him for his sin in which he has sinned, and he shall have forgiveness.
