I believe there are so many underlying stories in the Bible that we readers overlook. I also believe that if a story is in the bible there is a reason for it. Find me a history and or religion that has been so thoroughly searched out to be destroyed and failed completely. This fact in itself should give some hesitation to dismissing the Bible.
I’ve found this website that lists “obscure” characters but if this captures your interest I encourage you to do some research for there are many more out there.
