Leviticus 9:6-8

English Standard Version Anglicised

⁶ And Moses said, “This is the thing that the Lord commanded you to do, that the glory of the Lord may appear to you.” ⁷ Then Moses said to Aaron, “Draw near to the altar and ^(A)offer your sin offering and your burnt offering and ^(B)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.
