Exodus 29:33-34

Brenton(i) 33 They shall eat the offerings with which they were sanctified to fill their hands, to sanctify them; and a stranger shall not eat of them, for they are holy. 34 And if aught be left of the flesh of the sacrifice of consecration and of the loaves until the morning, thou shalt burn the remainder with fire: it shall not be eaten, for it is a holy thing.
