Leviticus 9:1-7

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

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

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

4and an ox and a ram for peace offerings, to sacrifice before the LORD; and a meal offering mingled with oil: for today the LORD appeareth unto you.

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

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