1 Now the serpent was more subtil than any beast of the field which the LORD God had made. And he said unto the woman, Yea, hath God said, Ye shall not eat of every tree of the garden?
2 And the woman said unto the serpent, We may eat of the fruit of the trees of the garden:
3 But of the fruit of the tree which is in the midst of the garden, God hath said, Ye shall not eat of it, neither shall ye touch it, lest ye die.
4 And the serpent said unto the woman, Ye shall not surely die:
5 For God doth know that in the day ye eat thereof, then your eyes shall be opened, and ye shall be as gods, knowing good and evil.
Now, did the serpent mean: It is certain that you will not die? Or did he mean: It is not certain that you will die? Is this a purposeful ambiguity? Funny that there should be this element of doubt right at the beginning, when knowledge is given to man. Skepticism is at the root, shall we say.
Is the serpent inviting Eve into a structured risky venture, this knowlege business? An invitation to risk assessment? Perhaps she did a quick cost-benefit analysis, and it came out positive for benefit.
