I believe in the genuine parts, the parts that have not been the thoughts of the imaginations of the ancient scribes.If word of mouth does not work, then the Quaran is all worthless as it was passed by word of mouth, stories told and retold and was not written down for centuries after it was dictated to Mohammad. Mohammad told the whole thing from memory, another word of mouth.
I believe the Bible. Many have put it to the test and it passes every time.
Why do you quote a book you don't believe at its face value. You can't believe some of it and not other parts as it suits your agenda.
The true exodus, was that of the HYKSOS (foreign rulers) and that is recorded in the Egyptian history.
The exodus of hebrew slaves was all made up.
You are not even aware that circumsiion came out of Egypt. see drawing on the tomb of ankhmahor then explain that to me, note they are 13 years old youths, not 8 day old babies.
Read in Genesis chapter 50, How Jacob was mummified as an Egyptian mummy and how all Egypt mourned him.
See How Joseph was also embalmed as a mummy.
Abram and Yaqubel were Hyksos kings they were of Amorite stock.
Read in your bible where Ezekiel speaking to Jerusalem said,'Your father was an Amorite and your mother was an Hittite.
Read how Abram was a goy,, as for me behold my covenant is with you, and you shall be a father of many nations.
Goy =nation. Goyim=nations.
The Goy and goyim became a derogatory words.
Both Abram and Yaqub both came from Mesopotamia, they were not related but only from the same country of birth.
Look up lists of the Hyksos kings there you will find MAABRA which became the anagram of ABRAAM.
See the name of Yaqubel also a ruling pharaoh. They were not slaves but kings. Who ruled in lower Egypt, in Avaris.
So the scribes had to give you a Hebrew slave Exodus otherwise you have no story!.
There is not one word of this mass exodus in Egyptian history. And there is not a trace of an Hebrew slave exodus to be found in the Sinai desert.
