I found a very interesting passage. It is Deuteronomy 32:8. Let's take a look:
YLT Deut 32:8 In the Most High causing nations to inherit, In His separating sons of Adam--He setteth up the borders of the peoples By the number of the sons of Israel.
As you can see, Written Torah implies that Hebrews are proportional to the rest of the human population.
This is very interesting.
Officially, there are 14 million Jews. This is of'course, only one tribe (Judah). This means that there are other tribes (who are not self-aware) since there are over 7 billion people right now.
This also explains why there were such heavy casualties in the World War 2. Jewish people were being exterminated, which caused proportional reduction in the populations of other nations (i.e Russian).
We are said to be priests to the nations, which means that every single Hebrew is responsible for numerous people from other nations. This is a big responsibility, so we must preach only truth, only Written Torah. And we must set the example for everyone else.
