Well, I've heard Bible scholars assert that he'll be from Rome or from the revived Roman empire. But what I'm finding in my search refutes that.
I was curious about the 7 hills being 7 kings, 5 have passed, one is and one is not yet. The beast which was and is not, is himself also an eighth, and is one of the seven...
The beast (not the dragon (satan) or the false prophet) would not be #7 but I believe one of the others and he died. So who are the 7 kings? Do they clone him from some old DNA?
