Judah is a subset of Israel. They will ultimately reunite in G-D's time.
I totally agree with you on that 100%...
I do have a question for you on race and the bible. Would you consider by biblical knowledge Adam and Eve to be Semitic?
By no means. Adam & Eve had 3 sons, Cain, Abel and Seth. Cain killed Abel and was banished by G-D. Seth was the only survivor.
The descendants of Shem the son of Noah are the Semites.
Europeans are generally considered to be descendants of Yefeth (Japhet).
As far as Biblical lineage is concerned, Sannharib the Assyrian (who conquered the 10 Tribes) pretty much wiped out their lineage by dispersing and mingling all his conquests. The Judeans resisted, but they were dispersed by the Romans.
In these times, "Jews" are all those people who:
1. Practice the Jewish religion
2. Can track their ancestors to people who practiced the Jewish religion.
3. Convert according to the halachah (religious law) of the Jewish religion.
This does NOT include practicing Christians or Muslims. Such people MUST accept Judaism in order to be considered Jewish.
Do you suffer from short-term memory loss? I think that I have answered this same question from you a number of times.
They were before the Flood. Shem was the son of Noah, and the father of the Semites. It was post diluvian, and after Adam.
