Leviticus 9:3-5

3Then tell the Israelites, ‘Take a male goat for a sin offering, and take a calf and a lamb, both a year old and without defects, for a burnt offering.

4Also take a bull and a ram for a peace offering and flour moistened with olive oil for a grain offering. Present all these offerings to the Lord because the Lord will appear to you today.’”

5So the people presented all these things at the entrance of the Tabernacle, just as Moses had commanded. Then the whole community came forward and stood before the Lord.
