Ezekiel 4:12-14 NLT

12 Each day prepare your bread 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.
13 For this is what the LORD says: Israel will eat defiled bread in the Gentile lands, where I will banish them!"
14 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 that I found dead. And I have never eaten any of the animals that our laws forbid."
