Leviticus 8:1-6

¹And the LORD spoke to 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 assemble thou all the congregation to the door of the tabernacle of the congregation.

⁴And Moses did as the LORD commanded him; and the assembly was gathered to the door of the tabernacle of the congregation.

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

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