2:5ב׳:ה׳
1 א

לרחץ על היאר. סָרֵס הַמִּקְרָא וּפָרְשֵׁהוּ: ותרד בת פרעה על היאר לרחץ בו:

לרחץ על היאר — Invert the order of the words in this verse and then explain it: “The daughter of Pharaoh went down על היאר, by the river, לרחץ to bathe in it”.

על יד היאר. אֵצֶל הַיְאוֹר, כְמוֹ "רְאוּ חֶלְקַת יוֹאָב אֶל יָדִי" (שמואל ב י"ד), וְהוּא לְשׁוֹן יָד מַמָּשׁ, שֶׁיַּד הָאָדָם סְמוּכָה לוֹ. וְרַבּוֹתֵינוּ אָמְרוּ, "הוֹלְכוֹת" לְשׁוֹן מִיתָה (סוטה י"ב), כְּמוֹ "הִנֵּה אָנֹכִי הוֹלֵךְ לָמוּת" (בראשית כ"ה) – הוֹלְכוֹת לָמוּת לְפִי שֶׁמִּחוּ בָהּ; וְהַכָּתוּב מְסַיְּעָן, כִּי לָמָּה לָנוּ לִכְתֹּב וְנַעֲרוֹתֶיהָ הוֹלְכוֹת:

על יד היאר means BESIDE THE RIVER. Similar is (II Samuel 14:30) “See, the field of Joab is beside mine (על ידי)”. It really denotes even in this sense the actual hand, for a person’s hand is beside him (i. e. beside his body). Our Rabbis explained that the word הלכת “they were going” denotes dying, similar to (Genesis 25:32) “Behold I am going (הולך) to die” — they were going to their death because they attempted to prevent her from saving the child. Scripture, too, supports them in this explanation, for if this is not the meaning, why do we need that it should write “and her damsels were going”? (Scripture reports nothing as having happened because they were walking there. Why then stress this detail if it merely signifies that they were walking along the bank?).

את אמתה. אֶת שִׁפְחָתָהּ. וְרַבּוֹתֵינוּ דָּרְשׁוּ (סוטה שם), לְשׁוֹן יָד, אֲבָל לְפִי דִּקְדּוּק לְשׁוֹן הַקֹּדֶשׁ הָיָה לוֹ לְהִנָּקֵד אַמָּתָהּ, דְּגוּשָׁה, וְהֵם דָּרְשׁוּ אֶת אֲמָתָהּ – אֶת יָדָהּ, וְנִשְׁתַּרְבְּבָה אַמָּתָהּ אַמּוֹת הַרְבֵּה:

את אמתה means her handmaid. Our Rabbis, however, explained it in the sense of hand (cf. Sotah 12b) — but according to the grammar of the Holy Language it should then have been written אַמָּתָה , dageshed in the מ. — And the reason why they explained את אמתה to mean את ידה “she stretched forth her hand” is because they hold that Scripture intentionally uses this term to indicate that her hand increased in length several cubits (אמה, a cubit) in order that she might more easily reach the cradle.
