Leviticus 8:31-33

31Then Moses said to Aaron and to his sons, “Boil the meat at the doorway of the Tent of Meeting and eat it there together with the bread that is in the basket of the consecration (ordination) offering, just as I commanded, saying, ‘Aaron and his sons shall eat it.’

32And what remains of the meat and of the bread you shall burn in the fire.

33You shall not go outside the doorway of the Tent of Meeting for seven days, until the days of your consecration (ordination) are ended; for it will take seven days to consecrate you.
