Leviticus 8:31-33

31Then Moses said to Aaron and to his sons, “1Boil the flesh at the doorway of the tent of meeting, and eat it there together with the bread which is in the basket of the ordination offering, just as I commanded, 2saying, ‘Aaron and his sons shall eat it.’

32And 3the remainder of the flesh and of the bread you shall burn in the fire.

33And 4you shall not go outside the doorway of the tent of meeting for seven days, until the day that the period of your ordination is fulfilled; for he will 5ordain you through seven days.
