1Now the serpent was more crafty than any other beast of the field that the LORD God had made.
He said to the woman, "Did God actually say, 'You shall not eat of any tree in the garden'?" 2And the woman said to the serpent, "We may eat of the fruit of the trees in the garden, 3but God said, 'You shall not eat of the fruit of the tree that is in the midst of the garden, neither shall you touch it, lest you die.'" 4 But the serpent said to the woman, "You will not surely die. 5For God knows that when you eat of it your eyes will be opened, and you will be like God, knowing good and evil."
7Now war arose in heaven, Michael and his angels fighting against the dragon. And the dragon and his angels fought back, 8but he was defeated, and there was no longer any place for them in heaven. 9And the great dragon was thrown down, that ancient serpent, who is called the devil and Satan, the deceiver of the whole world— he was thrown down to the earth, and his angels were thrown down with him.
26Jesus answered, "It is he to whom I will give this morsel of bread when I have dipped it." So when he had dipped the morsel, he gave it to Judas, the son of Simon Iscariot. 27Then after he had taken the morsel, Satan entered into him. Jesus said to him, "What you are going to do, do quickly."
“I still did not know precisely when and why Beccah had become possessed. I knew that around age six she had developed an abnormal attraction to a book of woodcuts that told one version of the pact with the devil story,” M. Scott Peck, Glimpses of the Devil: A Psychiatrist’s Personal Accounts of Possession, Exorcism, and Redemption (Free Press 2005), 214-15.
“The extraordinary amount of restraint required was one of the less remarkable features of the exorcism. The most remarkable was the change in the appearance of Beccah’s face and body. Except during break times and a few other occasions when Satan would seemingly be replaced by Beccah, she did not appear to be a human being at all. To everyone present, her entire face became like that of a snake. I would have expected it to be the usual kind of poisonous snake with a triangular head, but that was not the case. The head and face of this snake were remarkably round. The only exception to this roundness was its nostrils, which had a distinct snub-nosed look. Most remarkable of all were the eyes. They had become hooded, ibid. 173.
“During another appointment, again for but a minute, Beccah’s face appeared to be that of a very dry, thick-skinned, lizardlike creature—possibly an iguana. Definitely a reptile but nothing like a snake,” ibid. 225.
