לכל עמו. אַף עֲלֵיהֶם גָּזַר (סוטה י"ב), יוֹם שֶׁנּוֹלַד מֹשֶׁה אָמְרוּ לוֹ אִצְטַגְנִינָיו, הַיּוֹם נוֹלָד מוֹשִׁיעָן, וְאֵין אָנוּ יוֹדְעִים אִם מִמִּצְרַיִם אִם מִיִּשְׂרָאֵל, וְרוֹאִין אָנוּ שֶׁסּוֹפוֹ לִלְקוֹת בַּמַּיִם, לְפִיכָךְ גָּזַר אוֹתוֹ הַיּוֹם אַף עַל הַמִּצְרִיִּים, שֶׁנֶּאֱמַר כָּל הַבֵּן הַיִּלּוֹד, וְלֹא נֶאֱמַר הַיִּלּוֹד לָעִבְרִים; וְהֵם לֹא הָיוּ יוֹדְעִים שֶׁסּוֹפוֹ לִלְקוֹת עַל מֵי מְרִיבָה:
לכל עמו This may be translated AND PHARAOH GAVE COMMAND REGARDING ALL (לכל) HIS PEOPLE — Regarding them, too, he made a decree (Sotah 12a). For on the day when Moses was born his astrologers said to him, “To-day their deliverer has been born, but we know not whether he is born of an Egyptian father or of an Israelite; but we see by our astrological art that he will ultimately suffer misfortune through water”. Pharaoh therefore made a decree that day regarding the Egyptians also, as it is said here, “Every son that is born [ye shall cast into the river]”, and it is not stated “[every son] who is born to the Hebrews”. They (the astrologers), however, were not aware that Moses was ultimately to suffer misfortune through the waters of Meribah and not through the waters of the Nile (Exodus Rabbah 1:18; Sotah 12a; cf. also Rashi on Numbers 20:13).
