Ezekiel 4:15

Then he said unto me, Lo, I have given thee cow’s dung for man’s dung, and thou shalt prepare thy bread therewith.

The verse belongs to a real acted miniature in which the siege of Jerusalem and its consequences were performed. In that sign Ezekiel endured a famine diet to portray the famine and suffering that would come upon Israel. The cow's dung was given as fuel for preparing bread as a substitute for human dung.

Ezekiel's eating of defiled bread prepared with cow's dung represented the food the children of Israel would eat during their Babylonian captivity among the Gentiles, typifying the awful judgments that awaited the Jews. That passage concerning the defiled bread refers to the time of Israel's captivity in Babylon. The defiled bread is the contempt with which the captives were satiated when their captors in scorn and derision asked why they did not sing one of their former joyful songs of praise. Seeing such terrible things in righteousness gives emphasis, positiveness, and dispatch to the message of those who have witnessed them.
