Charles Ellicott Commentary Ezekiel 37:23

"neither shall they defile themselves any more with their idols, nor with their detestable things, nor with any of their transgressions; but I will save them out of all their dwelling-places, wherein they have sinned, and will cleanse them: so shall they be my people, and I will be their God." — Ezekiel 37:23 (ASV)

Out of all their dwellingplaces.— This expression can hardly refer to their places of exile and temporary sojourn among the heathen, since these were not especially the places where they had sinned. Their sins were rather committed in their own land; the “lands of their captivity” were the places where those sins were punished.

“Their dwelling places” is then to be understood as their own land of Canaan, where they had been led into idolatry and all abominations by the heathen dwelling among them. The promise is that this land will be purged, that all evil will be cast out from it, and the people will be delivered from the temptations by which they had until now been overcome.
