'Serpent' in the Bible

Now the serpent was more subtle than any beast of the field which Jehovah God had made. And he said unto the woman, Yea, hath God said, Ye shall not eat of any tree of the garden?

And the woman said unto the serpent, Of the fruit of the trees of the garden we may eat:

And the serpent said unto the woman, Ye shall not surely die:

And Jehovah God said unto the woman, What is this thou hast done? And the woman said, The serpent beguiled me, and I did eat.

And Jehovah God said unto the serpent, Because thou hast done this, cursed art thou above all cattle, and above every beast of the field; upon thy belly shalt thou go, and dust shalt thou eat all the days of thy life:

Dan shall be a serpent in the way, An adder in the path, That biteth the horse's heels, So that his rider falleth backward.
