Leviticus 9:4-7

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 near, and they stood before the Lord.

⁶And Moses said, This is the thing which the Lord has spoken; do it, and the glory of the Lord shall appear among you.

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