THAT is the whole point. We do not know, if all we do is take a version as some men 500 years ago rewrote the original to fit their worldview of what it HAD to mean, and MUST have meant..... according to what THEY believed in the Medieval 1500's. If we do not know the original languages, we need to at least try to study people who have made it their life's work to attempt to understand what the ORIGINAL texts were saying.
