Charles Spurgeon Commentary Jeremiah 9:2

"Oh that I had in the wilderness a lodging-place of wayfaring men; that I might leave my people, and go from them! for they are all adulterers, an assembly of treacherous men." — Jeremiah 9:2 (ASV)

He mourned because of the doom that awaited them; but he equally mourned because of the sin that would bring that doom upon them. He wished that he could get away into one of those refuges, which were provided in lonely places, where travelers might lodge for a night.
