Exodus 29:26-34

“Now take the breast from Aaron’s ordination ram and wave it before GOD, a Wave-Offering. That will be your portion. “Bless the Wave-Offering breast and the thigh that was held up. These are the parts of the ordination ram that are for Aaron and his sons. Aaron and his sons are always to get this offering from the Israelites; the Israelites are to make this offering regularly from their Peace-Offerings. “Aaron’s sacred garments are to be handed down to his descendants so they can be anointed and ordained in them. The son who succeeds him as priest is to wear them for seven days and enter the Tent of Meeting to minister in the Holy Place. “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.
