Judah and Benjamin were Israelites.
remember that even 100,000 IS a vast number and definitely so in ancient times
Not against the world population claimed for those ancient times. Also, the population of Israel extrapolated form the number of fighting men in the Bible would have been several million. Many would have been killed by the Assyrians, but they had a couple of centuries to reclaim their numbers.
The Jews of the world number 24 MILLION AT LEAST
The last numbers I saw for present day Jews were about 4 or 5 million, this being acknowledged by Jews. Where did you get yours?
the Jewish Virtual Library lists the Jewish population of the world in the year 2003 as 13,296,100
