Leviticus 8:31-33

31Then Moses said to Aaron and his sons, “Boil the remaining meat of the offerings at the Tabernacle entrance, and eat it there, along with the bread that is in the basket of offerings for the ordination, just as I commanded when I said, ‘Aaron and his sons will eat it.’

32Any meat or bread that is left over must then be burned up.

33You must not leave the Tabernacle entrance for seven days, for that is when the ordination ceremony will be completed.
