Leviticus 9:4

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 to 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 to 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 to 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 to you.

7 And Moses said to Aaron, Go to 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.
