ויסעו מרפידים. מַה תָּ"לֹ לַחֲזֹר וּלְפָרֵשׁ מֵהֵיכָן נָסְעוּ, וַהֲלֹא כְבָר כָּתַב שֶׁבִּרְפִידִים הָיוּ חוֹנִים, בְּיָדוּעַ שֶׁמִּשָּׁם נָסְעוּ? אֶלָּא לְהַקִּישׁ נְסִיעָתָן מֵרְפִידִים לְבִיאָתָן לְמִדְבַּר סִינַי, מַה בִּיאָתָן לְמִדְבַּר סִינַי בִּתְשׁוּבָה, אַף נְסִיעָתָן מֵרְפִידִים בִּתְשׁוּבָה (מכילתא): ויסעו מרפידים AND THEY JOURNEYED FROM REPHIDIM — What does Scripture teach us by again expressly stating from where they set forth on the journey, for is it not already written (Exodus 17:1) that they had encamped at Rephidim and it is therefore evident that they set forth from there?! But Scripture repeats it in order to make a comparison with the character of their journey from Rephidim to that of their arrival in the wilderness of Sinai! How was it in the case of their arrival in the wilderness of Sinai? They were in a state of penitence (as shown by the unanimity with which they encamped before the mountain: cf. Rashi on the end of this verse)! Thus, too, their setting forth from Rephidim was in a state of repentance for the sin they had committed there (see Exodus 17:2) (Mekhilta d'Rabbi Yishmael 19:2:1).
ויחן שם ישראל. כְּאִישׁ אֶחָד בְּלֵב אֶחָד, אֲבָל שְׁאָר כָּל הַחֲנִיּוֹת בְּתַרְעוֹמוֹת וּבְמַחֲלֹקֶת: ויחן שם ישראל AND THERE ISRAEL ENCAMPED as one man and with one mind — but all their other encampments were made in a murmuring spirit and in a spirit of dissension (Mekhilta d'Rabbi Yishmael 19:2:10).
נגד ההר. לְמִזְרָחוֹ, וְכָל מָקוֹם שֶׁאַתָּה מוֹצֵא נֶגֶד, פָּנִים לַמִּזְרָח (שם): נגד ההר BEFORE THE MOUNTAIN — i. e. at its east side (Mekhilta d'Rabbi Yishmael 19:2:10), for wherever you find the word נגד referring to a locality it signifies with the face towards the east of the place mentioned.
