Leviticus 8:1-5

1And Yhwh spake unto Moses, saying,

2Take Aaron and his sons with him, and the garments, and the anointing oil, and a bullock for the sin offering, and two rams, and a basket of unleavened bread;

3And gather thou all the congregation together unto the door of the tabernacle of the congregation.

4And Moses did as Yhwh commanded him; and the assembly was gathered together unto the door of the tabernacle of the congregation.

5And Moses said unto the congregation, This is the thing which Yhwh commanded to be done.
