Ezekiel 4:12-15

12And thou shalt eat it [as] barley-cake, and thou shalt bake it in their sight with dung that cometh out of man.

13And Jehovah said, So shall the children of Israel eat their bread unclean among the nations whither I will drive them.

14Then said I, Ah, Lord Jehovah! behold, my soul hath not been defiled, and from my youth up even until now have I not eaten of that which dieth of itself, or of that which is torn; neither came there abominable flesh into my mouth.

15And he said unto me, See, I have given thee cow's dung for man's dung, and thou shalt prepare thy bread therewith.
