Leviticus 9:1-7

1On the eighth day Moses called Aaron and his sons and the elders of Israel,

2and he said to Aaron, "Take for yourself a bull calf for a sin offering and a ram for a burnt offering, both without blemish, and offer them before the Lord.

3And say to the people of Israel, 'Take a male goat for a sin offering, and a calf and a lamb, both a year old without blemish, for a burnt offering,

4and an ox and a ram for peace offerings, to sacrifice before the Lord, and a grain offering mixed with oil, for today the Lord will appear to you.'"

5And they brought what Moses commanded in front of the tent of meeting, and all the congregation drew near and stood before the Lord.

6And Moses said, "This is the thing that the Lord commanded you to do, that the glory of the Lord may appear to you."

7Then Moses said to Aaron, "Draw near to the altar and offer your sin offering and your burnt offering and make atonement for yourself and for the people, and bring the offering of the people and make atonement for them, as the Lord has commanded."
