The Jewish rabbis through the centuries have treated Genesis history as real history, with their ancient ancestors, and those of other people groups, having descended through the line of Shem, a son of Noah, down through Shem’s son Arphaxad (Chaldeans), and on down, as laid out precisely in Genesis 10, the “Table of Nations.”
And the rabbis have taught, and do teach, that the 72 basic languages of the world are from the 72 grandsons of Noah after the Tower of Babel, 16 of whom are listed in Genesis 10, and others not listed there, according to Jewish tradition, so post Deluge (during the Ice Age) humanity, as taught by the rabbis, descended from the three sons of Noah: Shem, Japheth, and Ham, who with their wives, survived the Deluge with the animals on the Ark.
But few rabbis today (I’m guessing) preach the literal Noah’s Flood which, according to their records, and Bishop Ussher’s, occurred circa 2400 B.C., counted by the generations as listed in Genesis. The tension is palpable, do we preach what the Torah says about ancient history, or do we make it allegorical when it plainly is not intended to be so?
I’m sure the rabbis, as well as Christian preachers, agonize over how to deal with the Noah story. If it’s merely allegory, then when does real history pick up, with Shem, with Abraham, where? And whenever that would be, then why would one pick that point in the narrative when the Genesis account is plainly a seamless rendering of the progress of history, generation by generation?
There is good evidence from Hebrew traditions, and from the information in article #13 at http://GenesisVeracity.com, that Genesis history was recorded history, on clay cuneiform tablets, so read that article, compare it to the Hebrew traditions about the records which were brought through the Deluge, and see that there is good reason for the rabbis and the Christian preachers to speak out about the veracity of Genesis history.
