There is a further intriguing clue that the Serpent was not only human, but that it was a demonically possessed woman. This hint stems from the definition and etymology of the Hebrew word translated as “serpent.” This word indicates that the Serpent may have shared the traits a demonically inhabited medium or soothsayer, who use indwelling familiar spirits to gain power and / or knowledge.
The word translated as Serpent is nachash (vxn – Strongs 5175). According to the Gesenius lexicon nachash comes from a root which means “to whisper” or “to hiss.” vxn can also mean “to divine”, or “to enchant” (Strongs 5172, 5173). Gesenius relates that this later meaning stemmed from the word describing the whispers of the soothsayers. Like modern day mediums or channelers, biblical soothsayers gained their powers through an indwelling demonic spirit. They spoke the words of these spirits in their trances. Also like modern mediums, these inhabited soothsayers were mostly women.
Nachash appears 31 times in the Bible with the meaning of serpent. 10 of those appearances are in reference to the Serpent of Eden. It appears 11 times with the meaning of “divination.”  Each time nachash is translated as serpent, it refers to a supernaturally inhabited creature of cursing. Nowhere in the Bible does nachash clearly refer to an ordinary snake.
The first time nachash is used in the Bible outside of Ge 3 is Ge 44:5. There it refers to divination. Nechash divination is mentioned 11 times in the Bible. Each time it is performed by humans. This implies that the Serpent could be a demonically inhabited human.
The ancient soothsayer corresponds to today’s modern channeler, who claims to have an indwelling spirit that temporarily takes over her body, animates her with its life-force, and thereby gives her knowledge or power. The indwelling demonic spirit of a soothsayer is called her familiar spirit. This familiar spirit is summoned by her so that it might inhabit her and thereby impart information or power to her. The soothsayer’s indwelling familiar spirit was either the spirit of the dead returned to earth, or the spirit of a soothsaying demon. Some believe that when the soothsayer professed to be indwelt with the spirit of the dead, they were in fact possessed by a demon falsely claiming to be that spirit.
In conclusion, the Hebrew word for Serpent provides evidence that it was no snake, but rather a demonically inhabited human. Furthermore, this human was an agent of cursing and very likely a female. The demonic inhabitation of the Serpent Lilith probably reflects the transformation which overcame her at her final rebellion, when she shouted the name of God, sprouted angelic type wings, and fled. Part of her transformation apparently included a demonic habitation. Perhaps Lucifer came home to dwell with his daughter.
 Nechash divination is mentioned in: Ge 30:27, 44:5, 44:15; Le 19:26; Nu 23:23, 24:1; De 18:10; 1Ki 20:33; 2Ki 17:17, 21:6; and 2Ch 33:6.
