Charles Ellicott Commentary Jeremiah 50:40

"As when God overthrew Sodom and Gomorrah and the neighbor cities thereof, saith Jehovah, so shall no man dwell there, neither shall any son of man sojourn therein." — Jeremiah 50:40 (ASV)

As God overthrew Sodom ... — The whole verse is reproduced from Jeremiah 49:18.

We enter here, indeed, upon a mosaic of quotations, or at least recollections of other prophecies.

For example, Jeremiah 50:41–43 are taken from Jeremiah 6:22-24, where “Babylon” is substituted for “Zion,” and “the king of Babylon” for “we.” Likewise, Jeremiah 50:44–46 are taken from Jeremiah 49:19-21, with the necessary substitutions of “Babylon” for “Edom,” “the Chaldeans” for “Teman,” and “among the nations” for “in the Red Sea.”

The reader is referred accordingly to the Notes on those passages.

The reproduction in identical terms is probably connected with the thoughts of retribution, on which the prophet dwells in Jeremiah 50:15. All that she had done, Babylon was now to suffer.
