Leviticus 8:31-33

31Moses told Aaron and his sons: “Cook the meat at the entrance to the tent of meeting. Take the meat and the bread in the basket of the ordination offering. Eat them there as I commanded when I said, ‘Aaron and his sons will eat it.’

32You must burn any meat or bread that is left over.

33You will not leave the entrance to the tent of meeting for seven days, not until the last day of your ordination is over. It will take seven days to ordain you.
