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: Exo 12:10, 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.
