Leviticus 9:3

1 And it came to pass on the eighth day, that Moses called Aaron and his sons, and the elders of Israel;

2 And he said unto Aaron, Take thee a young calf for a sin offering, and a ram for a burnt offering, without blemish, and offer them before the LORD.

3 And unto the children of Israel thou shalt speak, saying, Take ye a kid of the goats for a sin offering; and a calf and a lamb, both of the first year, without blemish, for a burnt offering;

4 Also a bullock and a ram for peace offerings, to sacrifice before the LORD; and a meat offering mingled with oil: for to day the LORD will appear unto you.

5 And they brought that which Moses commanded before the tabernacle of the congregation: and all the congregation drew near and stood before the LORD.

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

7 And Moses said unto Aaron, Go unto the altar, and offer thy sin offering, and thy burnt offering, and make an atonement for thyself, and for the people: and offer the offering of the people, and make an atonement for them; as the LORD commanded.
