Exodus 29:31-34

31And thou shalt take the ram of the consecration, and boil its flesh in a holy place.

32And Aaron and his sons shall eat the flesh of the ram, and the bread that is in the basket, at the entrance of the tent of meeting.

33They shall eat the things with which the atonement was made, to consecrate [and] to hallow them; but a stranger shall not eat [of them], for they are holy.

34And if [any] of the flesh of the consecration, and of the bread, remain until the morning, then thou shalt burn the remainder with fire: it shall not be eaten, for it is holy.
