(יג) אֵ֣לֶּה הַמִּצְוֺ֞ת וְהַמִּשְׁפָּטִ֗ים אֲשֶׁ֨ר צִוָּ֧ה יי בְּיַד־מֹשֶׁ֖ה אֶל־בְּנֵ֣י יִשְׂרָאֵ֑ל בְּעַֽרְבֹ֣ת מוֹאָ֔ב עַ֖ל יַרְדֵּ֥ן יְרֵחֽוֹ׃
(13) These are the commandments and regulations that the LORD enjoined upon the Israelites, through Moses, on the steppes of Moab, at the Jordan near Jericho.
(א) אֵ֣לֶּה הַדְּבָרִ֗ים אֲשֶׁ֨ר דִּבֶּ֤ר מֹשֶׁה֙ אֶל־כָּל־יִשְׂרָאֵ֔ל בְּעֵ֖בֶר הַיַּרְדֵּ֑ן בַּמִּדְבָּ֡ר בָּֽעֲרָבָה֩ מ֨וֹל ס֜וּף בֵּֽין־פָּארָ֧ן וּבֵֽין־תֹּ֛פֶל וְלָבָ֥ן וַחֲצֵרֹ֖ת וְדִ֥י זָהָֽב׃
(1) These are the words that Moses addressed to all Israel on the other side of the Jordan.—Through the wilderness, in the Arabah near Suph, between Paran and Tophel, Laban, Hazeroth, and Di-zahab,
(א) אלה הדברים. לְפִי שֶׁהֵן דִּבְרֵי תוֹכָחוֹת וּמָנָה כַאן כָּל הַמְּקוֹמוֹת שֶׁהִכְעִיסוּ לִפְנֵי הַמָּקוֹם בָּהֵן, לְפִיכָךְ סָתַם אֶת הַדְּבָרִים וְהִזְכִּירָם בְּרֶמֶז מִפְּנֵי כְבוֹדָן שֶׁל יִשְׂרָאֵל (עי' ספרי):
(1) אלה הדברים THESE ARE THE WORDS — Because these are words of reproof and he is enumerating here all the places where they provoked God to anger, therefore he suppresses all mention of the matters in which they sinned and refers to them only by a mere allusion contained in the names of these places out of regard for Israel (cf. Sifrei Devarim 1:1; Onkelos and Targum Jonathan).
(ד) בערבה. בִּשְׁבִיל הָעֲרָבָה, שֶׁחָטְאוּ בְּבַעַל פְּעוֹר בְּשִּׁטִּים בְּעַרְבוֹת מוֹאָב:
(4) בערבה IN THE PLAIN — i.e. he reproved them regarding the plain: that they had sinned through Baal Peor at Shittim in the plains of Moab (cf. Sifrei Devarim 1:13)
(ה) מול סוף. עַל מַה שֶּׁהִמְרוּ בְיַם סוּף בְּבוֹאָם לְיַם סוּף, שֶׁאָמְרוּ (שם י"ד) "הֲמִבְּלִי אֵין קְבָרִים בְּמִצְרַיִם", וְכֵן בְּנָסְעָם מִתּוֹךְ הַיָּם, שֶׁנֶּאֱמַר (תהילים ק"ו) "וַיַּמְרוּ עַל יָם בְּיַם סוּף" כִּדְאִיתָא בַּעֲרָכִין (דף ט"ו):
(5) מול סוף OVER AGAINST SUPH — i.e. he reproved them regarding that in which they had shown themselves rebellious at the Red Sea (סוף): viz., on their arrival at the Red Sea — that they said, (Exodus 14:11) “Is it because there are no graves in Egypt [that thou hast brought us to die in the wilderness?]"; and similarly when they left the midst of the Sea, as it is said, (Psalms 106:7) “They murmured because of the Sea, at the Red Sea”, as it is related in Treatise Arakhin 15a (cf. Rashi on Numbers 14:22 and Sifrei 1:14).
(ו) בין פארן ובין תפל ולבן. אָמַר רַבִּי יוֹחָנָן חָזַרְנוּ עַל כָּל הַמִּקְרָא וְלֹא מָצִינוּ מָקוֹם שֶׁשְּׁמוֹ תּוֹפֶל וְלָבָן, אֶלָּא הוֹכִיחָן עַל הַדְּבָרִים שֶׁתָּפְלוּ עַל הַמָּן, שֶׁהוּא לָבָן, שֶׁאָמְרוּ (במדבר כ"א) "וְנַפְשֵׁנוּ קָצָה בַּלֶּחֶם הַקְּלֹקֵל", וְעַל מַה שֶּׁעָשׂוּ בְמִדְבַּר פָּארָן עַל יְדֵי הַמְרַגְּלִים:
(6) בין פארן ובין תפל ולבן BETWEEN PARAN, AND TOPHEL AND LABAN — R. Jochanan said: We have gone through the whole Bible and we have found no place the name of which is Tophel or Laban! But the meaning is that he reproved them because of the calumnious statements (טפלו) they had made regarding the Manna which was white (לבן) in colour — that they said, (Numbers 21:5) “And our soul loathes this light bread”; and because of what they had done in the wilderness of Paran through the spies.
(ז) וחצרת. בְּמַחְלָקְתּוֹ שֶׁל קֹרַח; דָּבָר אַחֵר אָמַר לָהֶם הָיָה לָכֶם לִלְמוֹד מִמַּה שֶּׁעָשִׂיתִי לְמִרְיָם בַּחֲצֵרוֹת בִּשְׁבִיל לָשׁוֹן הָרָע, וְאַתֶּם נִדְבַּרְתֶּם בַּמָּקוֹם:
(7) וחצרת AND HAZEROTH — i.e. regarding wh‎at they had done there at the insurrection of Korah. — Another explanation: He said to them, “You ought to have taken a lesson from what I did to Miriam at Hazeroth because of the slander she uttered, and yet you even after that spoke against the Omnipresent (Sifrei Devarim 1:15).
(ח) ודי זהב. הוֹכִיחָן עַל הָעֵגֶל שֶׁעָשׂוּ בִּשְׁבִיל רוֹב זָהָב שֶׁהָיָה לָהֶם, שֶׁנֶּאֱמַר (הושע ב') "וְכֶסֶף הִרְבֵּיתִי לָהּ וְזָהָב עָשׂוּ לַבָּעַל" (עי' ספרי; בראשית ל"ב):
(8) ודי זהב AND DI ZAHAB (the name is taken in the sense of “sufficiency of gold”) — He reproved them on account of the golden calf which they had made in consequence of the abundance of gold which they had, as it is said, (Hosea 2:10) “And silver did I give them in abundance and gold: they, however, made it into a Baal” (cf. Berakhot 32a; Sifrei Devarim 1:18).

(א) אלה הדברים אשר דבר משה וכו'. במדבר בערבה מול סוף בין פארן ובין תופל. נראה לפרש שערבה הוא לשון ערב (דברים א, א). והנה בברייתו של עולם ערב קודם לבוקר כדאמרינן בריש ברכות. ואם כן תחלת ימי האדם נקראים ערב.לזה אמר בערבה מול סוף, דהיינו בהתחלת שנותיו של אדם תיכף יהיו כל מעשיו מול השכינה שנקראת סוף כידוע. בין פארן, כמו שדרשו רבותינו ז"ל שנקרא פארן שמשם יוצא פריה ורביה. ובין תופל, כמו שפירש רש"י לשון דיבור, והיינו שבין ברית המעור ובין ברית הלשון הכל יהיה מול סוף בקדושה ושמירה מעולה:

(1) Deuteronomy 1,1. “These are the words which Moses ‎spoke to the entire people of Israel in the desert, facing the ‎wilderness near Suph between Paran and between Tophel‏ ‏‎ ‎and Lavan.”
It seems reasonable to see in the word ‎ערבה‎, wilderness, a reference to the first time the word ‎ערב‎ ‎appears in the story of Creation (Genesis 1,5) where the meaning ‎is “evening,” a transition from day to night. At the time of the ‎creation the evening preceded the first morning, as before the ‎creation of light the universe had been in darkness, as we read ‎there in verse 2, and as the Talmud points out in the beginning of ‎tractate B’rachot, when discussing the times for reciting the ‎‎keriyat sh’ma. If we take our cue from that paragraph in the ‎Torah, the early years of our lives would be described as ‎ערב‎. ‎Having this in mind, the Torah, i.e. Moses, alludes here to the ‎need for every human being from his earliest youth to focus all of ‎his activities on the aspect of G’d familiar to us by the name ‎‎Shechinah, “G’d’s Presence.”‎
The deeper meaning behind the words: ‎בין פארן‎, is that this is ‎the site on earth from which the ability for living creatures on ‎earth to become fruitful and to multiply is derived. As to the ‎words: ‎ובין תפל‎, we follow Rashi, who quotes Rabbi Shimon ‎bar Yochai who claims that no one has ever been able to find ‎these two locations. He therefore concluded that these names are ‎similes, used by Moses to rebuke the Israelites who had spoken ‎derisively of the manna (Numbers 1,7), which was white, ‎לבן‎. The ‎word ‎תפל‎, [possibly as root of: ‎תפלה‎ “prayer”. Ed.], ‎according to Rashi, is another word for “speech” ‎‎(presumably Israel’s accepting the Torah with the words ‎נעשה ‏ונשמע‎, “we shall do and we shall listen (to instruction).” Moses’ ‎address teaching the Israelites to make G’d their focus at all times, ‎and to observe these covenants meticulously, covers the period ‎between the covenant of circumcision made with Avraham and ‎that of the Ten Commandments made with the assembled Jewish ‎nation at Mount Sinai.‎
