Ezekiel 4:12-15

And you shall eat it as barley cakes; and bake it using fuel of human waste in their sight.” Then the LORD said, “So shall the children of Israel eat their defiled bread among the Gentiles, where I will drive them.” So I said, “Ah, Lord GOD! Indeed I have never defiled myself from my youth till now; I have never eaten what died of itself or was torn by beasts, nor has abominable flesh ever come into my mouth.” Then He said to me, “See, I am giving you cow dung instead of human waste, and you shall prepare your bread over it.”
