Albert Barnes Commentary Ezekiel 24:3

"And utter a parable unto the rebellious house, and say unto them, Thus saith the Lord Jehovah, Set on the caldron, set it on, and also pour water into it:" — Ezekiel 24:3 (ASV)

A pot - Or, the caldron; with reference to (Ezekiel 11:3). The prophet indicates by the figure utter destruction. The caldron is the city, the fire is the surrounding army, the flesh and bones are the inhabitants shut in within the walls.
