Stories in law books aren't there with all their gruesome details to entertain the readers. They are there to demonstrate the reason for the laws or their application.
Well, I understood that line above to be clear enough. The stories were 'there to demonstrate (religious/national) laws'. That those laws were unique to a sect makes them sectarian laws. So my comment agreeing that there was a 'sectarian motive behind the stories' wasn't rooted in some dark hate for the Bible, it was agreeing with your comment. I don't know why you keep blowing up.
