I read with interest Julian Jaynes' Bicamerlism book where he claims that lenabe was mistranslated as "to prophetise" in LXX which also influenced Jewish thought. Later on, I wrote out of instinct that the "Greek philosphers, and similar phenomena such as the Hebrew Nevi'im were essentially entertainers," and it hit me and I hypothesised that "lenabe" actually meant "to philosophise / to dramatise / to entertain".
"beney hanevi'im" were actually full time entertainers who lived off donations, and weren't rich or had a day job, and were often considered as parasites in a similar way that actors, writers, "bloggers", youtubers, or reality show contestants are held in contempt today. "ben" in ancient Hebrew also meant "having the property of", and similarly I suspect that "beney haelohim" is an echo for the "self-leading people" ("conscious/sentient"? who knows)
So is it a popular theory among Biblical researchers?
Also note that I suspect that the David vs Goliath story was as funny then as the famous Gun vs. Swordman scene from the Indiana Jones, which has a similar (missile vs melee) structure, is today, it's just that the mentality back then was different (and some of us have some technological misconceptions).
