Genesis 3:1-7 Sin and the Serpent

I have been blessed to have in my possession a "Conservative" Jewish commentary on the Torah. (Genesis, Exodus, Leviticus, Numbers, and Deuteronomy) I was curious as to how it would view Genesis 3. Many Jews don't believe the devil is a real person. As I read this commentary on Genesis 3, it was titled, "the Transgression".
