Leviticus 8:33 (KJV)

And Moses took them from off their hands, and burnt them on the altar upon the burnt offering: they were consecrations for a sweet savour: it is an offering made by fire unto the LORD.

And Moses took the breast, and waved it for a wave offering before the LORD: for of the ram of consecration it was Moses' part; as the LORD commanded Moses.

And Moses took of the anointing oil, and of the blood which was upon the altar, and sprinkled it upon Aaron, and upon his garments, and upon his sons, and upon his sons' garments with him; and sanctified Aaron, and his garments, and his sons, and his sons' garments with him.

And Moses said unto Aaron and to his sons, Boil the flesh at the door of the tabernacle of the congregation: and there eat it with the bread that is in the basket of consecrations, as I commanded, saying, Aaron and his sons shall eat it.

And that which remaineth of the flesh and of the bread shall ye burn with fire.

As he hath done this day, so the LORD hath commanded to do, to make an atonement for you.

Therefore shall ye abide at the door of the tabernacle of the congregation day and night seven days, and keep the charge of the LORD, that ye die not: for so I am commanded.

So Aaron and his sons did all things which the LORD commanded by the hand of Moses.
