In weeks past, I would accept this kind of statement at face value. But since I am now familiar with your rather creative use of evidence, I think it would be good to actually LOOK at one of your examples of such “understanding”!
What is your example that “Jewish … expositors understood the flood as local” ?
Isn’t it just that they are trying to explain the survival of the Nephilm? OTHER than the Nephilm issue … do you have ANY OTHER references to the Genesis Flood that made Jewish readers think the flood was a regional flood?
