ויהי בשלח פרעה, ולא נחם. נְהָגָם, כְּמוֹ "לֵךְ נְחֵה אֶת הָעָם" (שמות ל"ב), "בְּהִתְהַלֶּכְךָ תַּנְחֶה אוֹתָךְ" (משלי ו'):

ויהי בשלח פרעה... ולא נחם AND IT CAME TO PASS WHEN PHARAOH HAD SENT [THE PEOPLE AWAY] THAT GOD GUIDED THEM NOT — The word נחם means He guided them, just as, (Exodus 32:34) “Go, guide (נחה) the people”, and (Proverbs 6:22) “when thou goest it shall guide (תנחה) thee”.

כי קרוב הוא. וְנֹחַ לָשׁוּב בְּאוֹתוֹ הַדֶּרֶךְ לְמִצְרַיִם; וּמִדְרְשֵׁי אַגָּדָה יֵשׁ הַרְבֵּה:

כי קרוב הוא BECAUSE IT WAS NEAR, and it would therefore be easy to return by the same route to Egypt. — Of Midrashic explanations there are many (cf. Mekhilta).

בראתם מלחמה. כְּגוֹן מִלְחֶמֶת "וַיֵּרֶד הָעֲמָלֵקִי וְהַכְּנַעֲנִי וְגוֹ'" (במדבר י"ד), אִם הָלְכוּ דֶּרֶךְ יָשָׁר הָיוּ חוֹזְרִים, וּמָה אִם כְּשֶׁהִקִּיפָם דֶּרֶךְ מְעֻקָּם אָמְרוּ "נִתְּנָה רֹאשׁ וְנָשׁוּבָה מִצְרָיְמָה" (שם), אִם הוֹלִיכָם בִּפְשׁוּטָה עַל אַחַת כַּמָּה וְכַמָּה:

בראתם מלחמה WHEN THEY SEE WAR — For instance the war mentioned in (Numbers 14:45) “Then the Amalekites and the Canaanites came down etc.” If they had proceeded by the direct route they would have then turned back. This is evident, for what would have been the case? If, when He led them about by a circuitous way, they said, (Numbers 14:4) “Let us appoint another chief and go back to Egypt”, had He led them by a direct route how much the more certainly would they have spoken so.

פן ינחם. יַחְשְׁבוּ מַחֲשָׁבָה עַל שֶׁיָּצְאוּ וְיִתְּנוּ לֵב לָשׁוּב:

פן ינחם PERADVENTURE [THE PEOPLE] REPENT — peradventure they cherish a different thought (they change their mind) about having gone out and set their hearts on returning (cf. Rashi on Genesis 6:6).

ויסב. הֱסִבָּם מִן הַדֶּרֶךְ הַפְּשׁוּטָה לַדֶּרֶךְ הָעֲקוּמָה:

ויסב means HE LED THE PEOPLE ABOUT from the direct route to a circuitous route.

ים סוף. כְּמוֹ לְיַם סוּף, וְסוּף הוּא לְשׁוֹן אֲגַם שֶׁגְּדֵלִים בּוֹ קָנִים, כְּמוֹ "וַתָּשֶׂם בַּסּוּף" (שמות ב'), "קָנֶה וָסוּף קָמֵלוּ" (ישעיהו י"ט):

ים סוף is the same as לים סוף TO THE RED SEA. The word סוף has the meaning of a marshy tract in which reeds grow; examples are: (Exodus 2:3) “She placed him in the reeds (בסוף)”; (Isaiah 19:6) “The flags and the reeds (וסוף) shall wither”.

וחמשים. אֵין חֲמוּשִׁים אֶלָּא מְזֻיָּנִים; (לְפִי שֶׁהֱסִבָּן בַּמִּדְבָּר הוּא גָּרַם לָהֶם שֶׁעָלוּ חֲמוּשִׁים, שֶׁאִלּוּ הֱסִבָּן דֶּרֶךְ יִשּׁוּב, לֹא הָיוּ מְחֻמָּשִׁים לָהֶם כָּל מַה שֶּׁצְּרִיכִין, אֶלָּא כְּאָדָם שֶׁעוֹבֵר מִמָּקוֹם לְמָקוֹם וּבְדַעְתּוֹ לִקְנוֹת שָׁם מַה שֶּׁיִּצְטָרֵךְ, אֲבָל כְּשֶׁהוּא פּוֹרֵשׁ לַמִּדְבָּר צָרִיךְ לְזַמֵּן לוֹ כָּל הַצֹּרֶךְ; וּמִקְרָא זֶה לֹא נִכְתַּב כִּי אִם לְשַׂבֵּר אֶת הָאֹזֶן, שֶׁלֹּא תִתְמַהּ בְּמִלְחֶמֶת עֲמָלֵק וּבְמִלְחֶמֶת סִיחוֹן וְעוֹג וּמִדְיָן מֵהֵיכָן הָיוּ לָהֶם כְּלֵי זַיִן שֶׁהִכּוּ אוֹתָם בַּחֶרֶב) וְכֵן הוּא אוֹמֵר "וְאַתֶּם תַּעַבְרוּ חֲמֻשִׁים" (יהושע א'), וְכֵן תִּרְגְּמוֹ אֻנְקְלוֹס "מְזָרְזִין", כְּמוֹ "וַיָּרֶק אֶת חֲנִיכָיו" (בראשית י"ד) – וְזָרֵיז. דָּבָר אַחֵר, חֲמֻשִׁים אֶחָד מֵחֲמִשָּׁה יָצְאוּ וְאַרְבָּעָה חֲלָקִים מֵתוּ בִּשְׁלֹשֶׁת יְמֵי אֲפֵלָה (מכילתא):

וחמשים — The word חמשים means provided with weapons (Mekhilta). — [Because He led them by a circuitous route through the wilderness He brought it about that they went up from Egypt well-provided; for had He led them circuitously by the route of an inhabited district they would not have provided for themselves every thing that they needed, but only a part, like a person who is travelling from place to place and intends to purchase there whatever he will require. But if he were setting out for the wilderness he must provide all that he will require. — This verse (statement in the verse) is written only with the view of making the ear understand (preparing you for a later statement) viz., that you should not wonder with regard to the war with Amalek and the war with Sihon and Og and Midian where they obtained weapons, since they smote them with the sword]. In a similar sense it says, (Joshua 1:14) “and ye shall pass over armed (חמשים)”. Onkelos, too, translated it by מזרזין which signifies “armed” in Aramaic, just as he translates the word וירק in (Genesis 14:14) וירק את חניכיו which means, “And he armed his trained servants” by וזריז. Another explanation of חמשים is: only one out of five (חמשה) went forth from Egypt, and four parts of the people died during the three days of darkness because they were unworthy of being delivered (Mekhilta; cf. Rashi on 10:22).

השבע השביע. הִשְׁבִּיעָם שֶׁיַּשְׁבִּיעוּ לִבְנֵיהֶם. וְלָמָּה לֹא הִשְׁבִּיעַ בָּנָיו שֶׁיִּשָּׂאוּהוּ לְאֶרֶץ כְּנַעַן מִיָּד כְּמוֹ שֶׁהִשְׁבִּיעַ יַעֲקֹב? אָמַר יוֹסֵף, אֲנִי שַׁלִּיט הָיִיתִי בְמִצְרַיִם וְהָיָה סֵפֶק בְּיָדִי לַעֲשׂוֹת, אֲבָל בָנַי לֹא יַנִּיחוּם מִצְרַיִם לַעֲשׂוֹת, לְכָךְ הִשְׁבִּיעָם לִכְשֶׁיִּגָּאֲלוּ וְיֵצְאוּ מִשָּׁם שֶׁיִּשָּׂאוּהוּ:

השבע השביע HE HAD STRAITLY ADJURED — He had made them swear that they would make their children swear. But why did he not make his sons swear that they would take him to the land of Canaan immediately on his death, as Jacob had made his sons swear? Joseph said: I was a ruler in Egypt and I had sufficient power to do what my father desired; but my sons — the Egyptians will not permit them to do this. Consequently he made them swear that when they would be delivered and would go forth from there that they would take him up with them (Mekhilta).

והעליתם את עצמתי מזה אתכם. לְאֶחָיו הִשְׁבִּיעַ כֵּן, לִמְּדָנוּ שֶׁאַף עַצְמוֹת כָּל הַשְּׁבָטִים הֶעֱלוּ עִמָּהֶם שֶׁנֶּאֱמַר אִתְּכֶם (מכילתא):

והעליתם את עצמתי מזה אתכם THEN YE SHALL BRING UP MY BONES AWAY HENCE WITH YOU — It was his brothers whom he made swear thus; consequently this tells us that they (the Israelites who left Egypt) must have brought up with them the bones of all Jacob’s sons (lit., the tribes) since it is said “with you” (with your own bones) (Mekhilta).

ויסעו מסכת. בַּיּוֹם הַשֵּׁנִי, שֶׁהֲרֵי בָרִאשׁוֹן בָּאוּ מֵרַעְמְסֵס לְסֻכּוֹת:

ויסעו מסכת AND THEY JOURNEYED FROM SUCCOTH — on the second day, for on the first day they had come from Rameses to Succoth (Exodus 12:37).

לנחתם הדרך. נָקוּד פַּתָּח שֶׁהוּא כְּמוֹ לְהַנְחוֹתָם, "לַרְאוֹתְכֶם בַּדֶּרֶךְ אֲשֶׁר תֵּלְכוּ בָהּ" (דברים א') שֶׁהוּא כְמוֹ לְהַרְאוֹתְכֶם, אַף כָּאן לְהַנְחֹתָם עַ"יְ שָׁלִיחַ, וּמִי הוּא הַשָּׁלִיחַ? עַמּוּד הֶעָנָן; וְהַקָּדוֹשׁ בָּרוּךְ הוּא בִּכְבוֹדוֹ מוֹלִיכוֹ לִפְנֵיהֶם, וּמִכָּל מָקוֹם אֶת עַמּוּד הֶעָנָן הֵכִין לְהַנְחוֹתָם עַל יָדוֹ, שֶׁהֲרֵי עַ"יְ עַמּוּד הֶעָנָן הֵם הוֹלְכִים; עַמּוּד הֶעָנָן אֵינוֹ לְאוֹרָה אֶלָּא לְהוֹרוֹתָם הַדֶּרֶךְ:

לנחתם הדרך TO GUIDE THEM IN THE WAY — It (the ל of לנחתם) is punctuated with Patach, because it (the word) is like לְהַנְחוֹתָם (being a contracted form of this); similar is, (Deuteronomy 1:33) “לַרְאֹתְכֶם the way in which ye shall go”, which is the same as לְהַרְאֹתְכֶם to show you. Thus, too, here: לנחתם means as much as להנחותם to make them be guided i. e. by means of an agent. And who was this agent? The pillar of cloud — and the Holy One, blessed be He, in His glory (Himself) led it before them. Nevertheless He Himself did not act as their immediate guide, but He provided the pillar of cloud that they might be guided by means of it, for, as a matter of fact, as the Scriptural account shows, it was by means of the pillar of cloud that they set forth on their journeys. The pillar of cloud was not for giving light to them but to show them the way.

לא ימיש. הַקָּבָּ"ה אֶת עמוד הענן יומם ועמוד האש לילה; מַגִּיד שֶׁעַמּוּד הֶעָנָן מַשְׁלִים לְעַמּוּד הָאֵשׁ וְעַמּוּד הָאֵשׁ מַשְׁלִים לְעַמּוּד הֶעָנָן, שֶׁעַד שֶׁלֹּא יִשְׁקַע זֶה עוֹלֶה זֶה:

לא ימיש means He — the Holy One, blessed be He — did not let depart (did not remove) את עמוד הענן יומם ועמוד האש לילה THE PILLAR OF CLOUD BY DAY NOR THE PILLAR OF FIRE BY NIGHT. — This tells us (we may gather from this) that the pillar of cloud handed over the camp to the pillar of fire and the pillar of fire handed it over to the pillar of cloud — that before the one set the other rose (Shabbat 23b).

וישבו. לַאֲחוֹרֵיהֶם, לְצַד מִצְרַיִם הָיוּ מְקָרְבִין כָּל יוֹם הַשְּׁלִישִׁי, כְּדֵי לְהַטְעוֹת אֶת פַּרְעֹה שֶׁיֹּאמַר תּוֹעִים הֵם בַּדֶּרֶךְ, כְּמוֹ שֶׁנֶּאֱמַר "וְאָמַר פַּרְעֹה לִבְנֵי יִשְׂרָאֵל וְגוֹ'":

וישבו THAT THEY TURN backwards; all the third day they were moving nearer towards the Egyptians, in order to mislead Pharaoh, so that he should say: They have lost their way, as it is said, (v. 3) “so that Pharaoh will say of the children of Israel, [They are entangled in the land]”.

ויחנו לפני פי החירת. הוּא פִּיתוֹם, וְעַכְשָׁו נִקְרָא פִּי הַחִירֹת עַל שֵׁם שֶׁנַּעֲשׂוּ שָׁם בְּנֵי חֹרִין; וְהֵם שְׁנֵי סְלָעִים גְּבוֹהִים זְקוּפִים וְהַגַּיְא שֶׁבֵּינֵיהֶם קָרוּי פִּי הַסְּלָעִים:

ויחנו לפני פי החירת AND ENCAMP BEFORE PI-HAHIROTH — This is identical with Pithom (Mekhilta), but now it obtained the name of פי החירת, because there they became בני חורין free-men (חירת is explained as חרות freedom). This was two high, precipitous rocks and the valley between them was called פי הסלעים the mouth (opening) of the rocks.

לפני בעל צפן. הוּא נִשְׁאַר מִכָּל אֱלֹהֵי מִצְרַיִם כְּדֵי לְהַטְעוֹתָן, שֶׁיֹּאמְרוּ קָשָׁה יִרְאָתָן, וְעָלָיו פֵּרֵשׁ אִיּוֹב "מַשְׂגִּיא לַגּוֹיִם וַיְאַבְּדֵם" (איוב י"ב):

לפני בעל צפון BEFORE BAAL-ZEPHON — It (the idol of this name) alone had been left by God of all the gods of Egypt and, this, too, in order to mislead them — that they should say that their god was a difficult one to overcome. It was with reference to this that Job expressly said, (Job 12:23) “He causes the nations to err (מַשְׂגִיא, is taken in the sense of מַשְׁגִיא from root שגה to err) and then destroyeth them” (Mekhilta; cf. Rashi on this passage).

ואמר פרעה. כְּשֶׁיִּשְׁמַע שֶׁהֵם שָׁבִים לַאֲחוֹרֵיהֶם:

ואמר פרעה THEN PHARAOH WILL SAY — when he hears that they are turning back.

לבני ישראל. עַל בְּנֵי יִשְׂרָאֵל. וְכֵן (פסוק יד) "ה' יִלָּחֵם לָכֶם" – עֲלֵיכֶם, (בראשית כ יג) "אִמְרִי לִי אָחִי הוּא" – אִמְרִי עָלַי:

לבני ישראל means על בני ABOUT THE CHILDREN OF ISRAEL. Similarly. (v. 14) “The Lord will fight לכם”, i. e. עליכם for you; (Genesis 20:13) “Say לי, he is my brother” i. e. say about me.

נבכים הם. כְּלוּאִים וּמְשֻׁקָּעִים, וּבְלַעַז שירי"ר, כְּמוֹ "נִבְכֵי יָם" (איוב ל"ח), "בְּעֵמֶק הַבָּכָא" (תהילים פ"ד) "מִבְּכִי נְהָרוֹת" (איוב כ"ח).

נבכים הם means, shut up and sunk deep. old French serrer. Of similar meaning are (Job 38:16) “the depths of (נבכי) the sea”; (Psalms 84:7) “in the vale of dejection (הבכא)”; (Job 28:11) “from the depths (מבכי) of the rivers.”

נבכים הם, כְּלוּאִים הֵם בַּמִּדְבָּר, שֶׁאֵינָן יוֹדְעִין לָצֵאת מִמֶּנּוּ וּלְהֵיכָן יֵלֵכוּ:

נבכים הם means THEY ARE SHUT UP in the wilderness — so that they do not know how to get out of it and whither they should go.

ואכבדה בפרעה. כְּשֶׁהַקָּבָּ"ה מִתְנַקֵּם בָּרְשָׁעִים שְׁמוֹ מִתְגַּדֵּל וּמִתְכַּבֵּד, וְכֵן הוּא אוֹמֵר "וְנִשְׁפַּטְתִּי אִתּוֹ וְגוֹ'" וְאַחַר כָּךְ "וְהִתְגַדִּלְתִּי וְהִתְקַדִּשְׁתִּי וְנוֹדַעְתִּי וְגוֹ'" (יחזקאל ל"ח), וְאוֹמֵר "שָׁמָּה שִׁבַּר רִשְׁפֵי קָשֶׁת", וְאַחַר כָּךְ "נוֹדָע בִּיהוּדָה אֱלֹהִים" (תהלים ע"ו), וְאוֹמֵר "נוֹדַע ה' מִשְׁפָּט עָשָׂה" (שם ט'):

ואכבדה בפרעה AND I WILL BE HONOURED THROUGH PHARAOH — When the Holy One, blessed be He, takes vengeance on the wicked His name is magnified and honoured. Thus, too, it states, (Ezekiel 38:22, 23) “And I will plead against him [with pestilence and with blood etc.]”, and afterwards, “Thus I shall be magnified and sanctified etc.” And it states, (Psalms 76:3) “There He broke the fiery shafts of the bow”, and afterwards (after He has done this) (v. 2) “In Judah is God known. “Further it states, (Psalms 9:17) “The Lord is known because He executeth judgment” (Mekhilta).

בפרעה ובכל חילו. הוּא הִתְחִיל בַּעֲבֵרָה וּמִמֶּנּוּ הִתְחִילָה הַפֻּרְעָנוּת:

בפרעה ובכל חילו THROUGH PHARAOH AND THROUGH ALL HIS FORCES — He began the wrongdoing and with him began the punishment (Mekhilta; cf. Rashi on Exodus 7:28).

ויעשו כן. לְהַגִּיד שִׁבְחָן, שֶׁשָּׁמְעוּ לְקוֹל מֹשֶׁה, וְלֹא אָמְרוּ הַאֵיךְ נִתְקָרֵב אֶל רוֹדְפֵינוּ? אָנוּ צְרִיכִים לִבְרֹחַ אֶלָּא אָמְרוּ אֵין לָנוּ לְקַיֵם אֶלָּא דִּבְרֵי בֶן עַמְרָם (מכילתא):

ויעשו כן AND THEY DID SO — This is stated in order to tell their praise — that they hearkened to Moses and did not say, How can we move nearer to our enemies; we ought rather to flee,” but they said, ‘‘It is ours only to carry out the bidding of the son of Amram” (cf. Mekhilta).

ויגד למלך מצרים. אִיקְטוֹרִין שָׁלַח עִמָּהֶם, וְכֵיוָן שֶׁהִגִּיעוּ לִשְׁלֹשֶׁת יָמִים שֶׁקָבְעוּ לֵילֵךְ וְלָשׁוּב וְרָאוּ שֶׁאֵינָן חוֹזְרִין לְמִצְרַיִם, בָּאוּ וְהִגִּידוּ לְפַרְעֹה בַּיּוֹם הָרְבִיעִי, בַּחֲמִישִׁי וּבַשִּׁשִּׁי רָדְפוּ אַחֲרֵיהֶם, לֵיל שְׁבִיעִי יָרְדוּ לַיָּם, בַּשַּׁחֲרִית אָמְרוּ שִׁירָה וְהוּא יוֹם שְׁבִיעִי שֶׁל פֶּסַח; לְכָךְ אָנוּ קוֹרִין הַשִּׁירָה בַּיּוֹם הַשְּׁבִיעִי:

ויגד למלך מצרים AND IT WAS TOLD THE KING OF EGYPT — He sent public officers with them, and as soon as they had reached the three days’ journey which he had fixed for them to go and return, and these perceived that they were not going back to Egypt, they came and told Pharaoh on the fourth day (cf. Mekhilta). On the fifth and sixth they pursued after them: on the night of the seventh day they went down into the sea and on the following morning they (the Israelites) sang the Song of Praise and this was the seventh day of Passover. And that is why we read “The Song” (Exodus 15:1 ff.) as the Scriptural lesson on the seventh day of the Festival (Megillah 31a; Seder Olam 5; cf. Sotah 12b).

ויהפך. נֶהְפַּךְ מִמַּה שֶּׁהָיָה, שֶׁהֲרֵי אָמַר לָהֶם "קוּמוּ צְּאוּ מִתּוֹךְ עַמִּי" (שמות י"ב), וְנֶהְפַּךְ לֵב עֲבָדָיו, שֶׁהֲרֵי לְשֶׁעָבַר הָיוּ אוֹמְרִים לוֹ "עַד מָתַי יִהְיֶה זֶה לָנוּ לְמוֹקֵשׁ" (שמות י'), וְעַכְשָׁיו נֶהֶפְכוּ לִרְדֹף אַחֲרֵיהֶם בִּשְׁבִיל מָמוֹנָם שֶׁהִשְׁאִילוּם:

ויהפך [AND THE HEART…] WAS TURNED — it was turned (changed) from what it had been, because he had said to them (Exodus 12:31) “Arise, go out from the midst of my people”, and his servants’ hearts were changed because formerly they had said to him, (Exodus 10:7) “How long shall this man be a snare unto us? [let the men go etc.]”. Now, however, they (their hearts) were changed, prompting them to pursue them, because of the property that they had handed over to them (cf. Mekhilta).

מעבדנו. מֵעֲבֹד אוֹתָנוּ:

מעבדנו means from serving us (i. e. the word is an infinitive with an objective suffix and not a noun signifying “from our service”, which would require מֵעֲבוֹדָתֵנוּ).

ויאסר את רכבו. הוּא בְעַצְמוֹ (מכילתא):

ויאסר את רכבו AND HE MADE READY HIS CHARIOT — he himself (Mekhilta)

ואת עמו לקח עמו. מְשָׁכָם בִּדְבָרִים, לָקִינוּ וְנָטְלוּ מָמוֹנֵנוּ וְשִׁלַּחְנוּם, בֹּאוּ עִמִּי וַאֲנִי לֹא אֶתְנַהֵג עִמָּכֶם כִּשְׁאָר מְלָכִים, דֶּרֶךְ שְׁאָר מְלָכִים עֲבָדָיו קוֹדְמִין לוֹ בַּמִּלְחָמָה, וַאֲנִי אַקְדִּים לִפְנֵיכֶם, שֶׁנֶּאֱמַר וּפַרְעֹה הִקְרִיב – הִקְרִיב עַצְמוֹ וּמִהֵר לִפְנֵי חֵילוֹתָיו –, דֶּרֶךְ שְׁאָר מְלָכִים לִטֹּל בִּזָּה בָּרֹאשׁ כְּמוֹ שֶׁיִּבְחַר, אֲנִי אֶשְׁוֶה עִמָּכֶם בַּחֵלֶק שֶׁנֶּאֱמַר "אֲחַלֵּק שָׁלָל" (שמות ט"ו):

ואת עמו לקח עמו AND TOOK HIS PEOPLE WITH HIM — he drew them on by fine words, as follows: “We have been stricken and they have taken our money and yet we have let them go free. Come with me and I will not behave with you as other kings. It is the way of other kings that their subjects go in front of them into the battle, but I will go in front of you” — as, indeed, it is said, (v. 10) “And Pharaoh הקריב” (the Hiphil): which signifies he brought himself near and hastened in front of his army. — “It is the way of other kings to take the booty at the beginning as he chooses (to have first pick of the booty), but I will be equal to you in the division of the booty” — as, indeed, it states that he said, (Exodus 15:9) “I will divide the spoil”Mekhilta.

בחור. נִבְחָרִים, בָּחוּר לְשׁוֹן יָחִיד, כָּל רֶכֶב וָרֶכֶב שֶׁבְּמִנְיָן זֶה הָיָה בָּחוּר:

בחור means CHOSEN. The word בחור is singular number — the idea is: each and every chariot in that number was a selected one.

וכל רכב מצרים. וְעִמָּהֶם כָּל שְׁאָר הָרֶכֶב; וּמֵהֵיכָן הָיוּ הַבְּהֵמוֹת הַלָּלוּ? אִם תֹּאמַר מִשֶּׁל מִצְרַיִם, הֲרֵי נֶאֱמַר "וַיָּמָת כֹּל מִקְנֵה מִצְרָיִם" (שמות ט'), וְאִם מִשֶּׁל יִשְׂרָאֵל, וַהֲלֹא נֶאֱמַר "וְגַם מִקְנֵנוּ יֵלֵךְ עִמָּנוּ", מִשֶּׁל מִי הָיוּ? מִן הַיָּרֵא אֶת דְּבַר ה'. מִכָּאן הָיָה רַ' שִׁמְעוֹן אוֹמֵר, כָּשֵׁר שֶׁבַּמִּצְרִים הֲרֹג, טוֹב שֶׁבַּנְּחָשִׁים רְצֹץ אֶת מֹחוֹ (מכילתא):

וכל רכב מצרים signifies AND with these were ALL THE other CHARIOTS OF EGYPT. And whence came all these animals required for the chariots? If you say that they were from the cattle of the Egyptians — but you know it is stated, (Exodus 9:6) “And all the cattle of the Egyptians died”. And if you say that they were from the Israelites’ cattle — but is it not stated, (Exodus 10:26) “Our cattle, also, shall go with us”! Then whose were they? They were of those “who feared the word of the Lord” and saved their cattle by bringing them into their stables (Exodus 9:20). Deriving it from here (on account of this fact) R. Simeon said: The best amongst the Egyptians — kill him (otherwise he will afterwards devise evil against you); the best amongst the serpents — crush its brains (Mekhilta).

ושלשם על כלו. שָׂרֵי צְבָאוֹת, כְּתַרְגּוּמוֹ:

ושלשים על כלו means army-captains, as the Targum has it.

ויחזק ה' את לב פרעה. שֶׁהָיָה תוֹלֶה אִם לִרְדֹּף אִם לָאו, וְחִזֵּק אֶת לִבּוֹ לִרְדֹּף (שם):

ויחזק ה׳ את לב פרעה AND THE LORD ALLOWED THE HEART OF PHARAOH TO BE HARDENED — the meaning is, that he was in doubt whether to pursue or not, and He hardened his heart to pursue (Mekhilta).

ביד רמה. בִּגְבוּרָה גְּבוֹהָה וּמְפֻרְסֶמֶת:

ביד רמה WITH A HIGH HAND — with high and open daring (cf. Mekhilta).
