Leviticus 9:5-7

⁵And they brought that which Moses commanded before the tent of meeting: and all the congregation drew near and stood before Jehovah.

⁶And Moses said, This is the thing which Jehovah commanded that ye should do: and the glory of Jehovah shall appear unto you.

⁷And Moses said unto Aaron, Draw near unto the altar, and offer thy sin-offering, and thy burnt-offering, and make atonement for thyself, and for the people; and offer the oblation of the people, and make atonement for them; as Jehovah commanded.
