Leviticus 9:6-8

Amplified Bible

⁶ Moses said, “This is the thing which the Lord has commanded you to do, so that the glory of the Lord may appear to you.” ⁷ Moses said to Aaron, “Approach the altar and present your sin offering and your burnt offering and make atonement for yourself and for the people; and present the offering of the people and make atonement for them, just as the Lord has commanded.”^(A)

⁸ So Aaron approached the altar and killed the calf as the sin offering, which was designated for himself.
