Moses does not need to have been Osarsiph or have starred in Freud’s fiction, to have gained something from the Akhenaten episode which occurred in the century before his time.
St Stephen, testifying to the Sanhedrin (the Jewish theocracy) just before his martyrdom in the years shortly after the Christ’s Resurrection, pointed out that ‘Moses was learned in all the wisdom of the Egyptians’ during his earlier life at the Pharaoh’s court, ‘and was mighty in words and in deeds’ (Acts of the Apostles chapter 7, verse 22).
By that date in Ancient Egypt the history of Akhenaten’s reign may have been known to privileged high-ranking Egyptians in the same way that Orwell’s writings were permitted reading for the Soviet Politburo; and Akhenaten’s monotheism could have fed into Moses’ preparatio evangelica, his being readied for his encounter with the true God at the Burning Bush.
This tends to happen to people who encounter the way, the truth, the life and are converted to it. It chimes with what they previously have learned or studied or experienced, makes sense of those phenomena, putting in order all the scattered pieces of the jigsaw puzzle of their existence to date and making of those shards of truth one coherent revelation.
What are the dates of the ‘Letters found in archives across the Near East’ which ‘speak of plague gods’?
If they were written about 1250-1230 BC, may they not relate to the Ten Plagues which afflicted Egypt at Moses’ behest?
That ‘In the Egyptian version’ of the Exodus ‘the “Jews” are shown as lepers, as impure people, atheists, misanthropes, iconoclasts, vandals, and sacrilegious criminals’ stands to reason.
How else would most Egyptians perceive a people which had called down upon them plagues of boils, lice, their waters all turned to blood, a murrain on their cattle, terrible giant hailstones, the death of all their firstborn?
I doubt if the townsfolk of Hamelin in retrospect had nice things to say about the Pied Piper.
