Nice, almost subtle switch there, Ben, but how you interpret things is irrelevant. The point is, if Jews don't believe in demons, as you had your little ignoramus fictional character (not the member on this board) Thomas say, then Samael, the so called "Prince of demons," as the writer put it, sure got an inexplicably long article of his own in the Jewish Encyclopedia I cited.
Metaphorically. If he meant literally, he would have got no chance to be published in the Jewish Encyclopedia. There is no such a thing as Greek Mythology in Judaism.
