I have been looking for an authentic Jewish approach to the question of the unique instance of the highly specific future reference in Breishit 36:31:
ואלה המלכים אשר מלכו בארץ אדום לפני מלך־מלך לבני ישראל
These are the kings who reigned in the land of Edom before any king reigned over the Israelites.
but I can only find Christian commentators. Are there Jewish sources that discuss this issue (e.g. did the Jewish people know the future Edomite kings before they came to power, why are there no other similarly specific references to the future in the Chumash, is the text authentic or addition, etc.).
