Leviticus 9:7-8
Leviticus 9:7-8 AMP
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.” [Heb 5:1-5; 7:27] So Aaron approached the altar and killed the calf as the sin offering, which was designated for himself.
