The Torah says Eve saw the tree was good for food. Targum Pseudo-Jonathan on (Genesis 3:6) tells us she also saw something else.
"The woman beheld Samael, the angel of death, and was afraid." Samael, in later midrashic and Kabbalistic tradition, is the celestial being who rides the serpent — the accuser and the prosecutor. In Jewish thought, Samael is not an independent evil power; he is an angel of the heavenly court, sometimes identified with ha-Satan, the Accuser, fulfilling a role God permits. But he is terrifying nonetheless. Eve sees him and is afraid.
And then — this is the tragedy — she eats anyway. The Targumist refuses to let us read her action as naive. She knew something was wrong. She saw the shadow behind the serpent. "Yet she knew that the tree was good to eat, and that it was medicine for the enlightenment of the eyes, and a desirable tree by means of which to understand." The appeal of the fruit overwhelmed the fear. She took, she ate, and she gave her husband beside her, and he ate.
Why fear did not stop her
This verse teaches something hard. Knowing that a thing is dangerous, even seeing the angel of death standing next to it, is not always enough. Desire can outrun fear. Adam did not even get to see Samael — he just received the fruit from his wife and ate. The Targumist distributes responsibility carefully: Eve sinned with her eyes open; Adam sinned by not asking any questions. Both forms of failure are equally real.
