Cool find. I assumed it was Assyrian because it's apparently the name of an Assyrian MMA fighter.
I found this website (
http://www.atour.com/education/assyriannames.html) that lists a Bineil (perhaps a different spelling?) and it says the meaning is "build". But idk, very cool name though.
It's pronounced like "ben-YOOL" or "ben-YUHL"?
