Leviticus 8:31-33

31And Moses spoke to Aaron and to his sons, Boil the flesh at the entrance of the tent of meeting; and there eat it and the bread that is in the basket of the consecration-offering, 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 entrance of the tent of meeting seven days, until the day when the days of your consecration are at an end: for seven days shall ye be consecrated.
