⁴and a calf and a ram for a peace offering before the Lord, and fine flour mingled with oil, for today the Lord will appear among you.

⁵And they took as Moses commanded them before the tabernacle of witness, and all the congregation drew nigh, and they stood before the Lord.

— Leviticus 9:6 —

⁷And Moses said to Aaron, Draw nigh to the altar, and offer thy sin offering, and thy whole burnt offering, and make atonement for thyself, and for thy house; and offer the gifts of the people, and make atonement for them, as the Lord commanded Moses.

⁸And Aaron drew nigh to the altar, and slew the calf of his sin offering.
