Charles Ellicott Commentary Ezekiel 22:19

"Therefore thus saith the Lord Jehovah: Because ye are all become dross, therefore, behold, I will gather you into the midst of Jerusalem." — Ezekiel 22:19 (ASV)

Into the midst of Jerusalem. —Jerusalem is represented as the refining pot into which the people were to be cast, because this was at once their national centre, and also the centre of the war by which they were carried into captivity.
