“Man, I’m having to dig thru my brain but I read a book 30 years ago about the differentiation between Sephardic (which I recall as indigenous, darker skinned genetic original Jews, and the Ashkenazi who were largely converts(?) who went up into Europe.
Someone please beat me with a stick ; I’m no historian or scholar.”
I think Google could be your friend.
Maybe google my basement.
Don’t know if the book was accurate at all, but it was at least an insight to the Diaspora for this gentile.

Stuff I hadn’t thought much about before or since. We were seeking keys to prophecy as I recall.
We were all worried about the European Common Market and its 10 or 12 horns....
I know there is a true seed of Jacob that plays an important role in the end times, but I consider myself a Gentile and have enough trouble keeping up with that.
