Exodus 29:32-34

Revised Standard Version

³² and Aaron and his sons shall eat the flesh of the ram and the bread that is in the basket, at the door of the tent of meeting. ³³ They shall eat those things with which atonement was made, to ordain and consecrate them, but an outsider shall not eat of them, because they are holy. ³⁴ And if any of the flesh for the ordination, or of the bread, remain until the morning, then you shall burn the remainder with fire; it shall not be eaten, because it is holy.
