Deuteronomy 32:32 Their vine comes from the vine of Sodom and from the fields of Gomorrah. Their grapes are filled with poison, and their clusters with bitterness.

Josephus Flavius (37-94 CE), The Wars of the Jews, Book IV, 8:4) The country of Sodom borders upon it. It was of old a most happy land, both for the fruits it bore and the riches of its cities, although it be now all burnt up. It is related how, for the impiety of its inhabitants, it was burnt by lightning; in consequence of which there are still the remainders of that Divine fire, and the traces [or shadows] of the five cities are still to be seen, as well as the ashes growing in their fruits; which fruits have a color as if they were fit to be eaten, but if you pluck them with your hands, they dissolve into smoke and ashes.
