Exodus 29:31-34

31“Take the ram used in the ordination ceremony, and boil its meat in a sacred place.

32Then Aaron and his sons will eat this meat, along with the bread in the basket, at the Tabernacle entrance.

33They alone may eat the meat and bread used for their purification in the ordination ceremony. No one else may eat them, for these things are set apart and holy.

34If any of the ordination meat or bread remains until the morning, it must be burned. It may not be eaten, for it is holy.
