I'm quite sure John 8:7 has multiple interpretations, not just the one you ascribe to it...whatever that is.
You can either tell me or we're done.
No, there's only one interpretation. But to understand it you would need to:
Understand the specific law the woman was accused of, how it is determined, who is punished...
You would have to understand which authority does the judging... How the due process normally works...
How Yeshua must have had authority over the woman (and what that likely authority was), as his decision overrode normal due process...
And you would need to understand the entire concept of 'The First Stone' - who had the right to throw it, what the concept was for, and which authority could have that right if the first holder could not be found (as set out in Torah).
Needless to say, a fairly involved process to inform you (which I would be happy to do), but which would be a lengthy sidebar - Perhaps better left for another time. If you are indeed interested, I have given you enough to find out on your own, or PM me if you'd like to continue...
