Leviticus 9:3-5

3And tell the Israelites: Take a male goat for a sin offering; a calf and a lamb, male yearlings without blemish, for a burnt offering;

4an ox and a ram for a fellowship offering to sacrifice before the Lord; and a grain offering mixed with oil. For today the Lord is going to appear to you.”

5They brought what Moses had commanded to the front of the tent of meeting, and the whole community came forward and stood before the Lord.
