Ancient jews did not spread too much beyond the borders of the promised land

Lost many wars to other peoples
Enslaved by the Egyptians
Barely any technological advancements

I am a jew and my people are dumb.

Jews are known for the bible, for being lawyers, for everything with high verbal iq

But they can't engineer, invent or build. Barely any concept of math is mentioned in the bible and talmud.

Why are so dumb except in the verbal department? How is an ethnic group so good at one cognitive field while being borderline nigger in others?
