וַיֹּ֕אמֶר אֶת־קֹלְךָ֥ שָׁמַ֖עְתִּי בַּגָּ֑ן וָאִירָ֛א כִּֽי־עֵירֹ֥ם אָנֹ֖כִי וָאֵחָבֵֽא׃
Il répondit: "J’ai entendu ta voix dans le jardin; j’ai eu peur, parce que je suis nu, et je me suis caché."
Sforno on Genesis
ואירא, this feeling of fear is similar to that experienced by the Jewish people in Exodus 34,30 when, because of the sin of the golden calf, the people were afraid to face him after his face radiated light when he returned from Mount Sinai.
Radak on Genesis
ויאמר..כי עירום אנכי, the word עירום is again spelled with the letter י serving to elongate the syllable commencing with the letter ע.
Haamek Davar on Genesis
And I was afraid because I was naked: He explained that he did not run away because of fear that he would be punished, but rather because he was naked and it is not respectful to the Divine Presence. And that is awe of the sublime.
