Exodus 29:32-34

Amplified Bible

³² Aaron and his sons shall eat the meat of the ram and the bread in the basket, at the doorway of the Tent of Meeting. ³³ They shall eat those things by which atonement was made at their ordination and consecration; but a layman shall not eat them, because they are holy [that is, set apart to the worship of God]. ³⁴ And if any of the meat of ordination or the bread remains until morning, you shall burn it in the fire; it shall not be eaten, because it is holy.
