So is Cain a wordplay on "purchase" and the snake decieving can mean "loaning" "hiring" "Indebting" or something along those lines. So when Eve said
>The serpent deceived meit means Eve was loaned something, from which cain, the serpent seed (this text here makes a really good case for the Cain being the offspring of Eve and the Serpent while Abel is from Adam and Eve
http://theopenscroll.com/cainsPaternity.htm ), the purchase was born. The same wordplay between decieve or credited/loaned also fits "snakebite". This means the deception is the loan/credit which is the deadly venomous bite of snake/creditor. The word "Canaan" is also related to Cain and means as much as "commerce" or "trade". The Canaanites are as I believe off spring of Cain. So the snake indebted Eve and Adam, which created the purchase, cain, which resulted in Adam and Eve leaving paradise. The purchase or trade, Cain, also becomes the first murderer. The land of Canaan, the land of trade and commerce is where todays Israel is. Canaanites by this definition are everyone who fell for the greed of the commerce, and these are also the same people the God told his people to completly wipe out.
When later Noah got drunk on wine making Ham see his Nakedness (Usually seen as either raping Noah, his father, or fucking Noahs wife/his mother) this is also a play on word meaning that he was hired. By hiring/loaning his father he raped him. Later when the bible speaks of nations or persons getting drunk on the wine it implies them loaning money, which makes them feel like drunk, euphoric, resulting in degeneracy, blasphemy and evil in general through the spirit of commerce that dwells in them.
However I believe this is just one of many meanings of Genesis which are all right and important
