Exodus 29:33-34

AKJV(i) 33 And they shall eat those things with which the atonement was made, to consecrate and to sanctify them: but a stranger shall not eat thereof, because they are holy. 34 And if ought of the flesh of the consecrations, or of the bread, remain to the morning, then you shall burn the remainder with fire: it shall not be eaten, because it is holy.
