2:25ב׳:כ״ה
1 א

ולא יתבוששו. שֶׁלֹּא הָיוּ יוֹדְעִים דֶרֶךְ צְנִיעוּת לְהַבְחִין בֵּין טוֹב לָרָע, וְאַעַ"פִּ שֶׁנִּתְּנָה בוֹ דֵּעָה לִקְרוֹת לוֹ שֵׁמוֹת, לֹא נִתַּן בּוֹ יֵצֶר הָרָע עַד אָכְלוֹ מִן הָעֵץ וְנִכְנַס בּוֹ יֵצֶר הָרָע וְיָדַע מַה בֵּין טוֹב לָרָע (בראשית רבה):

ולא יתבוששו AND THEY WERE NOT ASHAMED — for they did not know what modestly meant, so as to distinguish between good and evil. Although he (Adam) had been endowed with knowledge to give names to all creatures, yet the evil inclination did not become an active principle in him until he had eaten of the tree, when it entered into him and he became aware of the difference between good and evil.
