Adam Clarke on Genesis 3:3

Neither shall ye touch it - Did not the woman add this to what God had before spoken? Some of the Jewish writers, who are only serious on comparative trifles, state that as soon as the woman had asserted this, the serpent pushed her against the tree and said, "See, thou hast touched it, and art still alive; thou mayest therefore safely eat of the fruit, for surely thou shalt not die."
