Leviticus 8:31-35

Moses spoke to Aaron and his sons: “Boil the meat at the entrance of the Tent of Meeting and eat it there with the bread from the basket of ordination, just as I commanded, saying, ‘Aaron and his sons are to eat it.’ Burn up the leftovers from the meat and bread. Don’t leave through the entrance of the Tent of Meeting for the seven days that will complete your ordination. Your ordination will last seven days. GOD commanded what has been done this day in order to make atonement for you. Stay at the entrance of the Tent of Meeting day and night for seven days. Be sure to do what GOD requires, lest you die. This is what I have been commanded.”
