בעצם היום. בּוֹ בַּיּוֹם שֶׁנִּצְטַוָּה, בַּיּוֹם וְלֹא בַּלַּיְלָה; לֹא נִתְיָרֵא לֹא מִן הַגּוֹיִם וְלֹא מִן הַלֵּצָנִים, וְשֶׁלֹּא יִהְיוּ אוֹיְבָיו וּבְנֵי דּוֹרוֹ אוֹמְרִים אִלּוּ רְאִינוּהוּ לֹא הִנַּחְנוּהוּ לָמוּל וּלְקַיֵּם מִצְוָתוֹ שֶׁל מָקוֹם:

בעצם היום IN THE SELFSAME DAY — on the very day when he received the command of circumcision: by day and not by night — he was afraid neither of the heathens nor of the cynics. And he did it in broad daylight in order that his enemies and other people should not say, “If we had seen him we would never have allowed him to practise circumcision and carry out the commandment of the Omnipresent (Genesis Rabbah 47:9).
