The Fall
The serpent deceived the woman, the man and woman ate from the forbidden tree, and God pronounced judgment on the serpent, the woman, and the man, expelling them from Eden while promising that the woman's offspring would crush the serpent's head (Genesis 3:15). Scripture does not state how long after creation this occurred; Ussher placed it in the first year.
1Now the serpent was more crafty than any beast of the field that the LORD God had made. And he said to the woman, “Did God really say, ‘You must not eat from any tree in the garden?’” 2The woman answered the serpent, “We may eat the fruit of the trees of the garden, 3but about the fruit of the tree in the middle of the garden, God has said, ‘You must not eat of it or touch it, or you will die.’”
