Read Heiser's article. The creatures that attack the Israelites are no mere snakes, but supernatural winged reptiles that serve the Hebrew God (or they are Yahweh's dragon buddies out for a good time).i Or they could be both, actually.
I unlike you actually read books in my education. Any serious student would rely on a Hebrew dictionary and Lexicon for a word definition. All of them state other wise to your folly. The great thing is that people can look it uo for themselves rather than twisting definitions. You and everyone here has not stepped up to the plate to even read one of the over 100 usages of the word "Saraph" to see it's true root word meaning. Also not one here has bothered to read the "Angelology" section of the un-authorized Jewish Encyclopedia which defines the "Seraphim" in the 10 order of Angels and calls them spirit beings. Again you and I hope any SERIOUS seeker would bother to look it up. Face it DC, you will never undo Judaism because I am sure they would laugh at the bible origins amateur website. I tell you what, if you actually get your "book" published other than by self publishing. I will buy several copies and personally send them to Tel Aviv University for their analysis.
