Ezekiel 4:10-14

Your food which you eat shall be twenty shekels a day by weight; you shall eat it from time to time.

The water you drink shall be a sixth of a hin by measure; you shall drink it from time to time.

You shall eat it as a barley cake, having baked it in their sight over human dung.”

Then the Lord said, “In this way the sons of Israel will eat their bread unclean among the nations where I will scatter them.”

But I said, “Oh, 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 animals, nor has any unclean meat ever entered my mouth!”
