Leviticus 9:3-6

9:3 Then tell the Israelites: ‘Take a male goat for a sin offering and a calf and lamb, both a year old and flawless, for a burnt offering, 9:4 and an ox and a ram for peace offerings to sacrifice before the Lord, and a grain offering mixed with olive oil, for today the Lord is going to appear to you.’” 9:5 So they took what Moses had commanded to the front of the Meeting Tent and the whole congregation presented them and stood before the Lord. 9:6 Then Moses said, “This is what the Lord has commanded you to do so that the glory of the Lord may appear to you.”
