Not surely

3:4 And the serpent said unto the woman, Ye shall not surely die:

Another verse ending in a colon.  I'd tack on a second verse here, but I have dinner plans.

First, she didn't say "Surely" in 3:3, although God did back in 2:17.  This suggests that the serpent already knew what the response would be (and knew it more accurately than the actual response).  Of course, it could just be the author getting sloppy.

The serpent is outright contradicting God.  In 2:17, God said, "In the day that thou eatest thereof thou shalt surely die."  Now, if Adam eats and dies, it's not clear, since "not surely" isn't quite as strong as "surely not".  But, should he survive, the only way to interpret it is that the serpent was right and God was wrong.  Or that the serpent was honest, and God was lying.
