Jamieson, Fausset and Brown on Ezekiel 24:3

3. pot--caldron. Alluding to the self-confident proverb used among the people, Eze 11:3 (see on Eze 11:3), "This city is the caldron and we be the flesh"; your proverb shall prove awfully true, but in a different sense from what you intend. So far from the city proving an iron, caldron-like defense from the fire, it shall be as a caldron set on the fire, and the people as so many pieces of meat subjected to boiling heat. See Jr 1:13.
