The first account we have of the devil is found in that purely scientific book called Genesis, and is as follows: "Now the serpent was more subtle 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 the fruit of the trees of the garden? And the woman said unto the serpent, We may eat of the fruit of the trees of the garden; 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. And the serpent said unto the woman, Ye shall not surely die. 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. And when the woman saw that the tree was good for food, and that it was pleasant to the eyes, and a tree to be desired to make one wise, she took of the fruit thereof and did eat, and gave also unto her husband with her, and he did eat.And the Lord God said Behold the man is become as one of us, to know good and evil; and now, lest he put forth his hand, and take also of the tree of life: and eat, and live forever. Therefore the Lord God sent him forth from the Garden of Eden to till the ground from which he was taken. So he drove out the man, and he placed at the east of the Garden of Eden cherubim and a flaming sword, which turned every way to keep the way of the tree of life."

According to this account the promise of the devil was fulfilled to the very letter, Adam and Eve did not die, and they did become as gods, knowing good and evil.
