Leviticus 8:31-33

31Moses said to Aaron and his sons, “Boil the meat at the entrance to the tent of meeting and eat it there with the bread that is in the basket for the ordination offering as I commanded: Aaron and his sons are to eat it.

32Burn up what remains of the meat and bread.

33Do not go outside the entrance to the tent of meeting for seven days, until the time your days of ordination are completed, because it will take seven days to ordain you.
