Again:
That does not follow from the biblical account. On the contrary, Eve knew from the beginning that THAT ONE and no other, was the tree whose fruit was forbidden even to touch. She was considering eating it for some time, until she ate it, and then she gave it to her husband to eat, and he willingly ate it.
Eve was deceived when Satan, like a ventriloquist, insisted that there was nothing wrong with eating it, and insinuated that God was lying, and forbidding them something that would benefit them.
Gen. 3:1 Now the serpent was the most cautious of all the wild animals of the field that Jehovah God had made. So it said to the woman:
“Did God really say that you must not eat from every tree of the garden?”
2 At this the woman said to the serpent:
“We may eat of the fruit of the trees of the garden. 3 But God has said about the fruit of the tree that is in the middle of the garden: ‘You must not eat from it, no, you must not touch it; otherwise you will die.’”
4 At this the serpent said to the woman:
“You certainly will not die. 5 For God knows that in the very day you eat from it, your eyes will be opened and you will be like God, knowing good and bad.”
6 Consequently, the woman saw that the tree was good for food and that it was something desirable to the eyes, yes, the tree was pleasing to look at. So she began taking of its fruit and eating it. Afterward, she also gave some to her husband when he was with her, and he began eating it.
Would God give a command so serious that it would involve the future of his creation, without giving specific and clear details about what was prohibited?
