Language, ethnicity, and religion are different things. Don't conflate them.

Linguistics is a very broad field of study. Forgive me if the analogy sounds condescending, but your question is like a horoscope reader asking "What is this huge body of research called astronomy, can you please point me to it?" Here is a bibliography with a focus on the historical linguistics of the Afroasiatic languages.

It is possible that Greek and Hebrew descend from a common ancestor, but this is not the same idea as "Hebrew is Greek." If they do, the evidence for it is weak and inconclusive, which is why there are very few linguists who claim to know this. I call this particular theory crackpot because in the very short time I spent looking at it, it was clear that the author and his proponents have an agenda that drives their thesis to ignore entire branches of scholarly inquiry that contradict what they prefer to be true.

Most people don't generally encounter linguistics in their studies, so it can be harder to spot dubious claims in that area. You seem like a smart and curious individual though, so I encourage you to read up on the field of historical linguistics while tackling this book. If you found out about this rare tome, I have no doubt you can figure out what books are good intros to historical linguistics.

All the best to you.
