This is great. Thanks for posting.
Not being too up on jew history (other than common knowledge), I'd love a little bit of actual history on this.
Do we have anything in writing which shows that jews worshipped Ramphan? I'd like to start there.
I think any source could be easily "debunked" since nowhere would it state, "we worship saturn/remphan".. but we know that Jesus called them the synagogue of satan. And that darkness has many names. Saturn worship has long been linked to satan worship. Etc..
According to texts written centuries after his death (1st to 5th century, roughly), it is speculated that he had a ring given to him by the archangel Michael which let him control demons.
You'll want to look for Testament of Solomon.
