Segment 1א׳
וְתָא חֲזֵי, מַה כְּתִיב וַיֹּאמְרוּ אִישׁ אֶל אָחִיו, דָּא שִׁמְעוֹן וְלֵוִי דְּאִינוּן הֲווּ אַחִין וַדַּאי בְּכֹלָּא, בְּגִין דְּקָא אָתוּ מִסִּטְרָא דְדִינָא קַשְׁיָא. וּבְגִין כָּךְ רוּגְזָא דִלְהוֹן, אִיהוּ רוּגְזָא דִּקְטָלָא בְּעַלְמָא. כְּמָה דְאַתְּ אָמֵר (בראשית מ״ט:ז׳) אָרוּר אַפָּם כִּי עָז וְעֶבְרָתָם כִּי קָשָׁתָה.
AND THEY SAID ONE TO ANOTHER (lit. one man to his brother). These are Simeon and Levi, who were truly brothers in all respects, both being descended from the side of rigorous judgement; and hence it was that their anger was the anger that causes death in the world, as it says: “Cursed be their anger, for it was fierce, and their wrath, for it was cruel” (Ibid. 49, 7).
Segment 2ב׳
תָּא חֲזֵי, רָזָא דְמִלָּה, אִית רוּגְזָא וְאִית רוּגְזָא. אִית רוּגְזָא דְּאִיהוּ מְבָרְכָא מֵעֵילָא וּמִתַּתָּא, וְאִקְרֵי בָּרוּךְ, כְּמָה דְאִתְּמָר דִּכְתִיב (בראשית י״ד:י״ט) בָּרוּךְ אַבְרָם לְאֵל עֶלְיוֹן קוֹנִה שָׁמַיִם וָאָרֶץ וְהָא אוּקְמוּהָ. וְאִית רוּגְזָא דְּאִיהִי אִתְלַטְיָא לְעֵילָא וְתַתָּא, כְּמָה דְאִתְּמָר דְּאִקְרֵי אָרוּר. דִּכְתִיב, (בראשית ג׳:י״ד) אָרוּר אַתָּה מִכָּל הַבְּהֵמָה וּמִכָּל חַיַּת הַשָּׂדֶה. אָרוּר אַפָּם כִּי עָז.
For there are two species of anger. There is anger which is blessed on high and below, and is called “blessed” (barukh), as explained in connection with the sentence: “Blessed be Abram of God Most High, Maker of heaven and earth” (Ibid. 14, 19); and there is anger which is accursed on high and is called “cursed” (arur), and regarding this it is written: “Cursed be thou from among all cattle, and from among all beasts of the field” (Ibid. 3, 14), as well as “Cursed be their anger for it was fierce.”
Segment 3ג׳
וְעַל רָזָא דָא אִית תְּרֵין טוּרִין דִּכְתִיב, (דברים י״א:כ״ט) וְנָתַתָּ אֶת הַבְּרָכָה עַל הַר גְּרִיזִים וְאֶת הַקְּלָלָה עַל הַר עֵיבָל, לָקֳבֵיל אִלֵּין תְּרֵין דַּרְגִּין. וְעַל דָּא, דָּא אִקְרֵי אָרוּר, וְדָא אִקְרֵי בָּרוּךְ. וְשִׁמְעוֹן וְלֵוִי אִינוּן מִסִּטְרָא דְדִינָא קַשְׁיָא, וּמִן סִטְרָא דְדִינָא קַשְׁיָא תַּקִּיפָא, נָפְקַת רוּגְזָא דְאִתְלַטְיָא.
This is the recondite significance of thc two mounts Gerizim and Ebal set aside for the blessing and the curse (Deut. 11, 29), the two mounts corresponding to these two grades; and hence one is called cursed and the other blessed. Simeon and Levi both belonged to the side of severity, from which side, in its extreme manifestation, issues the anger which is under a curse.
