Leviticus 8:1-5

The LORD said to Moses, “Bring Aaron and his sons and their clothes, the special olive oil used in appointing people and things to the service of the LORD, the bull of the sin offering and the two male sheep, and the basket of bread made without yeast. Then gather the people together at the entrance to the Meeting Tent.” Moses did as the LORD commanded him, and the people met together at the entrance to the Meeting Tent. Then Moses spoke to the people and said, “This is what the LORD has commanded to be done.”
