Exodus 29:34
And if ought of the flesh of the consecrations, or of the bread, remain unto the morning, then thou shalt burn the remainder with fire: it shall not be eaten, because it is holy.
And if ought of the flesh of the consecrations, or of the bread, remain unto the morning,.... Being more than the priests could eat:
then thou shalt burn the remainder with fire; that it might not be used in a contemptuous manner, or abused to superstitious uses; the same orders with those respecting what was left of the passover:
it shall not be eaten, because it is holy; which is the reason before given why it should not be eaten by a stranger, and being kept till the next morning it was ordered to be burnt, that it might not then be eaten at all; it was not to be given to a stranger, nor to be cast to dogs, because it had been devoted to sacred uses; and it seems as if it was not to be eaten by the priests themselves the next day, who were to live upon the daily provision made for them.
