Ezekiel 4:12-17

You shall eat it as a barley cake, having baked it in their sight over human dung.” Then the LORD said, “Thus will the sons of Israel eat their bread unclean among the nations where I will banish them.” But I said, “Ah, Lord GOD! Behold, I have never been defiled; for from my youth until now I have never eaten what died of itself or was torn by beasts, nor has any unclean meat ever entered my mouth.” Then He said to me, “See, I will give you cow’s dung in place of human dung over which you will prepare your bread.” Moreover, He said to me, “Son of man, behold, I am going to break the staff of bread in Jerusalem, and they will eat bread by weight and with anxiety, and drink water by measure and in horror, because bread and water will be scarce; and they will be appalled with one another and waste away in their iniquity.
