Ezekiel 4:15

“Then he said to me, &c.] The Lord hearkened to the prophet’s prayer and argument, and makes some abatement and alteration in the charge he gave him: lo, I have given thee cow’s dung for man’s dung: that is, allowed him to make use of the one instead of the other, in baking his mingled bread: thou shalt prepare thy bread therewith; having gathered cow’s dung, and dried it, he was to burn it, and bake his bread with it, which is meant by preparing it. In some parts of our nation, where fuel is scarce, cow’s dung is made use of; it is gathered and plastered on the walls of houses, and, being dried in clots, is taken and burnt.”

“cow's dung--a mitigation of the former order (Eze 4:12); no longer "the dung of man"; still the bread so baked is "defiled," to imply that, whatever partial abatement there might be for the prophet's sake, the main decree of God, as to the pollution of Israel by exile among Gentiles, is unalterable.”

“cow's dung: Dried cow-dung is a common fuel in the East, as it is in many parts of England, to the present day; but the prophet was ordered to prepare his bread with human ordure, to shew the extreme degree of wretchedness to which the besieged should be exposed, as they would be obliged literally to use it, from not being able to leave the city to collect other fuel.
