Leviticus 9:1-6

On the eighth day after the time of appointing, Moses called for Aaron and his sons and for the elders of Israel. He said to Aaron, “Take a bull calf and a male sheep that have nothing wrong with them, and offer them to the LORD. The calf will be a sin offering, and the male sheep will be a whole burnt offering. Tell the people of Israel, ‘Take a male goat for a sin offering and a calf and a lamb for a whole burnt offering; each must be one year old, and it must have nothing wrong with it. Also take a bull and a male sheep for fellowship offerings, along with a grain offering mixed with oil. Offer all these things to the LORD, because the LORD will appear to you today.’ ” So all the people came to the front of the Meeting Tent, bringing the things Moses had commanded them to bring, and they stood before the LORD. Moses said, “You have done what the LORD commanded, so you will see the LORD’s glory.”
