First of all, the episode art does not seem to correlate to a serpent. Well, let me tell you why.

I've also done a video on this as well. It may contain more information. Check it out if you're interested.

Upon my digging into Paleo Hebrew once again I made another discovery that just made sense. I parsed each letter of the Hebrew root nachash. There are three letters from right to left (you read right to left in Hebrew): Nun, Hhets and Shin. I will provide a paraphrased definition of their combined meaning. Nun can mean perpetuation. Hhets can mean a dividing wall. Shin can mean two or again perhaps as in repeated. So, the definition is "perpetual separator." This confirmed and supported many other verses and research. Here is my take on the being called the Nacash in the Garden. Enjoy!
