John Gill Commentary Ezekiel 6:6

"In all your dwelling-places the cities shall be laid waste, and the high places shall be desolate; that your altars may be laid waste and made desolate, and your idols may be broken and cease, and your sun-images may be hewn down, and your works may be abolished." — Ezekiel 6:6 (ASV)

In all your dwelling places your cities shall be laid waste, &c.] Which denotes that the desolation should be general, wherever they had cities and places to dwell in; the idolatry being universal, as is said in (Jeremiah 2:28).

And the high places shall be desolate; meaning such as were in cities; as, before, such as were built upon mountains and hills; see (2 Kings 23:5).

That your altars may be laid waste and desolate; as they must be, the cities being destroyed in which they were set up.

And your idols may be broken and cease, and your images may be cut down; such as were made of gold and silver, or of wood and stone; the same words are used for them as in (Ezekiel 6:4).

And your works may be abolished; not only the works of their hands, but of their brain; whatever they had devised, and was contrary to the pure word and worship of God.
