לנו ולמולדתנו. לְמִשְׁפְּחוֹתֵנוּ. וּמִדְרָשׁוֹ אֲפִלּוּ עֲצֵי עֲרִיסוֹתֵנוּ גִּלָּה לָנוּ: לנו ולמולדתנו CONCERNING OURSELVES AND CONCERNING OUR KINDRED — concerning our families. A Midrashic comment based upon the meaning of מולדת, “birth” — He asked of us concerning the circumstances of our birth — is: he could even tell us of what kind of wood our cradles were made (Genesis Rabbah 91:10).
ונגד לו. שֶׁיֵּשׁ לָנוּ אָב וְאָח: ונגד לו AND WE TOLD HIM that we had a father and a brother.
על פי הדברים האלה. עַל פִּי שְׁאֵלוֹתָיו אֲשֶׁר שָׁאַל, הֻזְקַקְנוּ לְהַגִּיד: על פי הדברים האלה ACCORDING TO THE TENOR OF THESE WORDS — we were forced to tell him according to the tenor of the questions he put to us.
כי יאמר. אֲשֶׁר יֹאמַר, כִּי מְשַׁמֵּשׁ בִּלְשׁוֹן אִם וְאִם מְשַׁמֵּשׁ בִּלְשׁוֹן אֲשֶׁר; הֲרֵי זֶה שִׁמּוּשׁ אֶחָד מֵאַרְבַּע לְשׁוֹנוֹתָיו שֶׁמְּשַׁמֵּשׁ כִּי, וְהוּא אִם, שֶׁהֲרֵי כִּי זֶה כְמוֹ אִם, כְּמוֹ עַד אִם דִּבַּרְתִּי דְּבָרָי (בראשית כ״ד:ל״ג): כי יאמר THAT HE WOULD SAY — The word כי is used here in the sense of אשר “that”. The word כי may be used in the sense of אם and אם may be used in the sense of אשר; therefore this (i.e. אשר) is one of the four meanings in which כי, according to the Rabbis, is used, viz., אם (Rosh Hashanah 3a), for the word כי here has the same meaning as אם, as in (24:33) עד אם דברתי דברי “until that I have spoken my words” (where אם is the same as כי or אשר).
