Leviticus 8:29-35

²⁹And Moses took the breast, and waved it for a wave-offering before the LORD; it was Moses' portion of the ram of consecration; as the LORD commanded Moses.

³⁰And 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.

³¹And Moses said unto Aaron and to his sons: 'Boil the flesh at the door of the tent of meeting; and there eat it and the bread that is in the basket of consecration, as I commanded, saying: Aaron and his sons shall eat it.

³²And that which remaineth of the flesh and of the bread shall ye burn with fire.

³³And ye shall not go out from the door of the tent of meeting seven days, until the days of your consecration be fulfilled; for He shall consecrate you seven days.

³⁴As hath been done this day, so the LORD hath commanded to do, to make atonement for you.

³⁵And at the door of the tent of meeting shall ye abide day and night seven days, and keep the charge of the LORD, that ye die not; for so I am commanded.
