Leviticus 8:31-36

And 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. And that which remaineth of the flesh and of the bread shall ye burn with fire. And 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. As hath been done this day, so Jehovah hath commanded to do, to make atonement for you. And at the door of the tent of meeting shall ye abide day and night seven days, and keep the charge of Jehovah, that ye die not: for so I am commanded. And Aaron and his sons did all the things which Jehovah commanded by Moses.
