Exodus 29:31-34

31“You are to take the ram of consecration and boil its meat in a holy place.

32Aaron and his sons are to eat the meat of the ram and the bread that is in the basket at the entrance of the Tent of Meeting.

33They are to eat those things with which atonement was made, to consecrate and to sanctify them, but a layman is not to eat them, because they are holy.

34If some of the meat of the consecration or the bread remains until the morning, you are to burn the remainder with fire. It shall not be eaten, because it is holy.
