Ezekiel 4:12-15

Eat the food as you would a barley cake. While everyone can see you, build a fire with dried human excrement, then bake the bread on the coals.” And YAHWEH said, “In this same way the Israelites will have to eat defiled food among the nations where I will disperse them.” Then I replied, “Oh no! Lord YAHWEH, I have never defiled myself, from childhood until now. I have never eaten meat from any animal that died a natural death or was killed by wild animals. Nothing unclean has ever entered my mouth.” “Very well,” he said, “I will let you use dried cow manure instead of human excrement as fuel to bake your bread.”
