Leviticus 8:31-33

31And Moses said to Aaron and his sons, “Boil the flesh at the door of the tabernacle of meeting, and eat it there with the bread that is in the basket of consecration offerings, as I commanded, saying, ‘Aaron and his sons shall eat it.’

32What remains of the flesh and of the bread you shall burn with fire.

33And you shall not go outside the door of the tabernacle of meeting for seven days, until the days of your consecration are ended. For seven days he shall consecrate you.
