Leviticus 8:1-6

1The Lord spoke to Moses, saying,

2"Take Aaron and his sons with him, and the garments and the anointing oil and the bull of the sin offering and the two rams and the basket of unleavened bread.

3And assemble all the congregation at the entrance of the tent of meeting."

4And Moses did as the Lord commanded him, and the congregation was assembled at the entrance of the tent of meeting.

5And Moses said to the congregation, "This is the thing that the Lord has commanded to be done."

6And Moses brought Aaron and his sons and washed them with water.
