Magdlyn, Great to see analysis of the old testament and polyamory. There are many lessons to be found, for example about restraint. Abraham didn't rush away from Sarah when she was barren. Instead, he stuck with her, but then she provided him with Hagar. After Sarah died, Abraham did marry again, and in my reading, have more than one wife. The Rabbis say it was actually Hagar, but we know better. Anyway, I will post about that someday and will look forward to your comments.
Cheers,
