Charles Ellicott 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)

Oh, that I had ...! —Literally, as before, Who will give ... ?

A lodging place of wayfaring men. —that is, a place of shelter, a khan or caravanserai, such as were built for travellers, such, e.g., as the inn of Genesis 42:27, the habitation of Chimham (Jeremiah 41:17), which the son of Barzillai had erected near Bethlehem, as an act of munificent gratitude to his adopted country (2 Samuel 19:40). In some such shelter, far from the cities of Judah, the prophet, with a feeling like that of the Psalmist (Psalms 55:6–8) would gladly find refuge from his treacherous enemies—“adulterers,” alike spiritually and literally (Jeremiah 5:8).
