Leviticus 8:31-33

31And Moses said to 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. 32And that which remaineth of the flesh and of the bread shall ye burn with fire. 33And ye shall not go out of the door of the tabernacle of the congregation in seven days, until the days of your consecration shall be at an end: for seven days shall he consecrate you.
