Albert Barnes Commentary Ezekiel 11:7

"Therefore thus saith the Lord Jehovah: Your slain whom ye have laid in the midst of it, they are the flesh, and this [city] is the caldron; but ye shall be brought forth out of the midst of it." — Ezekiel 11:7 (ASV)

All that will remain in the city are the buried dead. Bloodshed and murder were at this time rife in Jerusalem, and these were among the chief crimes that were bringing down judgment upon the city. All the inhabitants who were to survive were destined to be carried away into exile.
