God commands Ezekiel to bake his bread over human dung as a sign, and explains that it represents Israel eating unclean bread among the nations where they will be driven Ezekiel 4:12–13. When Ezekiel objects, God allows cow dung instead Ezekiel 4:14–15. The larger sign includes rationed bread and water showing siege scarcity Ezekiel 4:16–17.
In Ezekiel 4:12–13 Ezekiel is told to eat his ration as simple barley cakes and to bake them in public using human excrement as the fuel. Yahweh then explains the point of the shocking act: it portrays how Israel will have to eat “unclean” bread while living among foreign nations. These verses sit inside a larger set of enacted signs in Ezekiel 4 that portray the coming siege and its effects. Ezekiel is commanded to dramatize Jerusalem’s downfall through actions people can watch: building a miniature siege scene, lying on his side for set days, and eating tightly measured rations.
Ezekiel 4:12–13 presents a deliberately shocking sign. Ezekiel must eat his ration “as barley cakes,” and the key detail is how they are cooked: in public, using human excrement as fuel. The text itself then explains the meaning: in the same way, Israel will eat “unclean” bread while living among other nations, because Yahweh will drive them there.
A careful answer keeps the immediate passage, the book's argument, and the whole-Bible storyline together, so the question is answered in context instead of as a detached idea.

12You shall eat it as barley cakes, and you shall bake it in their sight with dung that comes out of man.
