'Serpent' in the Bible
Now the serpent was more crafty than any other {wild animal} which Yahweh God had made. He said to the woman, "Did God indeed say, 'You shall not eat from any tree in the garden'?"
The woman said to the serpent, "From the fruit of the trees of the garden we may eat,
But the serpent said to the woman, "You shall not surely die.
Then Yahweh God said to the woman, "What [is] this you have done?" And the woman said, "The serpent deceived me, and I ate."
Then Yahweh God said to the serpent, "Because you have done this, you [will be] cursed more than any domesticated animal and more than any wild animal. On your belly you shall go and dust you shall eat all the days of your life.
Dan shall be a serpent on the way, a viper on the road that bites the heels of a horse, so that its rider falls backward.
