Leviticus 9:6-8

Revised Standard Version Catholic Edition

⁶ And Moses said, “This is the thing which the Lord commanded you to do; and the glory of the Lord will appear to you.” ⁷ Then Moses said to Aaron, “Draw near to the altar, and offer your sin offering and your burnt offering, and make atonement for yourself and for the people; and bring the offering of the people, and make atonement for them; as the Lord has commanded.”

⁸ So Aaron drew near to the altar, and killed the calf of the sin offering, which was for himself.
