Sheelah, thank you for clarifying those terms which were unfamiliar to me in your response. It would appear my guess at El-Shaddai was way off! I don’t actually know any Hebrew but sometimes, while studying the Bible, I try to connect Hebrew words to one of the smattering of Arabic roots I’ve learned. I did a little poking around in dictionaries on this one. It looks like the /sh/ sound in the Hebrew El-Shaddai became a /th/ sound in a very similar Arabic root.
I saw Barker referenced in an article of James’ I read about a month ago. I had never heard of her before. I visited her website briefly that day, but I have yet to have an opportunity to read anything. She has written many books. Do let me know if you have a recommendation for a good entry point into her work.
