Exodus 29:31-34

“Take the ordination ram and boil the meat in the Holy Place. At the entrance to the Tent of Meeting, Aaron and his sons will eat the boiled ram and the bread that is in the basket. Atoned by these offerings, ordained and hallowed by them, they are the only ones who are to eat them. No outsiders are to eat them; they’re holy. Anything from the ordination ram or from the bread that is left over until morning you are to burn up. Don’t eat it; it’s holy.
