Leviticus 9:1-7

1On the eighth day Moses summoned Aaron and his sons and the elders of Israel. 2He said to Aaron, “Take for yourself a young bull for a sin offering and a ram for a burnt offering, both without blemish, and present them before the LORD. 3Then speak to the Israelites and say, ‘Take a male goat for a sin offering, a calf and a lamb—both a year old and without blemish—for a burnt offering, 4an ox1 and a ram for a peace offering to sacrifice before the LORD, and a grain offering mixed with oil. For today the LORD will appear to you.’”

5So they took what Moses had commanded to the front of the Tent of Meeting, and the whole congregation drew near and stood before the LORD. 6And Moses said, “This is what the LORD has commanded you to do, so that the glory of the LORD may appear to you.”

7Then Moses said to Aaron, “Approach the altar and sacrifice your sin offering and your burnt offering to make atonement for yourself and for the people. And sacrifice the people’s offering to make atonement for them, as the LORD has commanded.”
