Ruth is a fun book. It was the first book I read, when I was a child. The High Priestess in tarot comes to mind. Sitting between the 2 pillars B and J, Boaz is one, standing for strength. When reading the book of Ruth though, she is the strength.
Well, the book is around 3000 years old, while the Tarot is a few hundred. But the pillars are named after the pillars that stood at the entrance of The First Temple - 1 Kings 7:21. Is the second card with a high priestess a play or blasphemy on the Word of God? I don't know, but it seems like it.
