Re: ancient languages
You might take a look at Moses Was Not A Magician and see how the author picks out the ancient Egyptian loan word from the Hebrew/Chaldee text. Phoenician ..very similar to the Hebrew/Chaldee. You might look into ancient Sumerian or Akkadian writings too.

Re: Looking Within
Consider that when Moses came off the mountain he found them worshiping something without. But some suggest not just something, but the Bull of Hathor, a return to the Egypt in a sense?
