Ezekiel 4:12-15

Prepare and eat this food as you would barley cakes. While all the people are watching, bake it over a fire using dried human dung as fuel and then eat the bread.” Then the Lord said, “This is how Israel will eat defiled bread in the Gentile lands to which I will banish them!” Then I said, “O Sovereign Lord, must I be defiled by using human dung? For I have never been defiled before. From the time I was a child until now I have never eaten any animal that died of sickness or was killed by other animals. I have never eaten any meat forbidden by the law.” “All right,” the Lord said. “You may bake your bread with cow dung instead of human dung.”
