Commentaire sur La Genèse 3:5

כי ידע FOR [GOD] KNOWS — Every artisan detests his fellow-artisans (“Two of a trade never agree”). The serpent suggested to her: God ate of the tree and created the world (Genesis Rabbah 19:4) so if you eat ...

כי יודע...ונפקחו עיניכם He knows that your mental eyes will be opened to be like angel יודע טוב ורע, who know good and evil. The serpent had heard these words only from Chavah herself in her previous words. (verse 1)

And the eyes of both of them were opened: To see what is fit to be the way of the world, and what is not fit. Since even though the love of God wizens greatly, it nevertheless diverts the eye from the way of the world. And that is as it is found in Eruvin 54b, "They said of Rabbi Elazar ben Pedat that he would sit and engage in Torah study in the lower marketplace while his cloak was lying in the upper marketplace." And because of that, the man did not understand that it was not proper to stand naked in front of God. And all the more so did the woman not have [understanding of this] at all, but rather only [acted out of] love for her husband.
