Ezekiel 4:15-17

Then he said unto me, Lo, I have given thee cow's dung for man's dung, and thou shalt prepare thy bread therewith. Moreover he said unto me, Son of man, behold, I will break the staff of bread in Jerusalem: and they shall eat bread by weight, and with care; and they shall drink water by measure, and with astonishment: that they may want bread and water, and be astonied one with another, and consume away for their iniquity.
