@j @tyler I tried to find out more about this years ago. Here's what I found:

1. I can't find any historic description of the star of remphan, like what it looked like or how many points it had.
2. the star of david didn't start getting used as a jewish symbol extensively until the 12th century AD
3. I have found reference to an eight pointed star called star of remphan but this seems to be a red herring.
4. rempha is also a name for Saturn and you can find "star of saturn" and it's a star of david six pointed star. but this appears to be a much later occult thing, I can find no antiquity description of the star of saturn.

my conclusion was "probably no" but there's no way of knowing, it might be.
