Ezekiel 4:15

Then he said to me, See , I assign to you cow’s dung instead of human dung , on which you may prepare your bread .

“Very well,” he said, “I will let you bake your bread over cow dung instead of human excrement.”

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