נפל וגלוי עינים. פְּשׁוּטוֹ כְתַרְגּוּמוֹ — שֶׁאֵין נִרְאֶה עָלָיו אֶלָּא בַּלַּיְלָה כְּשֶׁהוּא שׁוֹכֵב; וּמִדְרָשׁוֹ: כְּשֶׁהָיָה נִגְלֶה עָלָיו לֹא הָיָה בוֹ כֹּחַ לַעֲמֹד עַל רַגְלָיו וְנוֹפֵל עַל פָּנָיו, לְפִי שֶׁהָיָה עָרֵל, וּמָאוּס לִהְיוֹת נִגְלֶה עָלָיו בְּקוֹמָה זְקוּפָה לְפָנָיו: נפל וגלוי עינים FALLING BUT HAVING HIS EYES OPEN — Its plain sense is as the Targum has it (“lying down when it was revealed to him”), meaning, that God revealed Himself to him only at night when he was lying on his bed. — And a Midrashic explanation of it is: When He revealed Himself to him he had no strength to stand on his feet, and he, therefore, fell on his face — because he was uncircumcised and it was therefore a loathsome thing that He should reveal Himself to him whilst he stood in an erect posture before Him (cf. Tar. Jon. and Rashi on Genesis 17:3).
