An Outcast In Both Worlds Parashat Vayigash 5779
(ל) וְעַתָּ֗ה כְּבֹאִי֙ אֶל־עַבְדְּךָ֣ אָבִ֔י וְהַנַּ֖עַר אֵינֶ֣נּוּ אִתָּ֑נוּ וְנַפְשׁ֖וֹ קְשׁוּרָ֥ה בְנַפְשֽׁוֹ׃ (לא) וְהָיָ֗ה כִּרְאוֹת֛וֹ כִּי־אֵ֥ין הַנַּ֖עַר וָמֵ֑ת וְהוֹרִ֨ידוּ עֲבָדֶ֜יךָ אֶת־שֵׂיבַ֨ת עַבְדְּךָ֥ אָבִ֛ינוּ בְּיָג֖וֹן שְׁאֹֽלָה׃ (לב) כִּ֤י עַבְדְּךָ֙ עָרַ֣ב אֶת־הַנַּ֔עַר מֵעִ֥ם אָבִ֖י לֵאמֹ֑ר אִם־לֹ֤א אֲבִיאֶ֙נּוּ֙ אֵלֶ֔יךָ וְחָטָ֥אתִי לְאָבִ֖י כָּל־הַיָּמִֽים׃ (לג) וְעַתָּ֗ה יֵֽשֶׁב־נָ֤א עַבְדְּךָ֙ תַּ֣חַת הַנַּ֔עַר עֶ֖בֶד לַֽאדֹנִ֑י וְהַנַּ֖עַר יַ֥עַל עִם־אֶחָֽיו׃ (לד) כִּי־אֵיךְ֙ אֶֽעֱלֶ֣ה אֶל־אָבִ֔י וְהַנַּ֖עַר אֵינֶ֣נּוּ אִתִּ֑י פֶּ֚ן אֶרְאֶ֣ה בָרָ֔ע אֲשֶׁ֥ר יִמְצָ֖א אֶת־אָבִֽי׃
(30) “Now, if I come to your servant my father and the boy is not with us—since his own life is so bound up with his— (31) when he sees that the boy is not with us, he will die, and your servants will send the white head of your servant our father down to Sheol in grief. (32) Now your servant has pledged himself for the boy to my father, saying, ‘If I do not bring him back to you, I shall stand guilty before my father forever.’ (33) Therefore, please let your servant remain as a slave to my lord instead of the boy, and let the boy go back with his brothers. (34) For how can I go back to my father unless the boy is with me? Let me not be witness to the woe that would overtake my father!”
(א) כי עבדך ערב את הנער. וְאִם תֹּאמַר, לָמָּה אֲנִי נִכְנָס לַתִּגָּר יוֹתֵר מִשְּׁאָר אַחַי? הֵם כֻּלָּם מִבַּחוּץ וַאֲנִי נִתְקַשַּׁרְתִּי בְקֶשֶׁר חָזָק לִהְיוֹת מְנֻדֶּה בב' עוֹלָמוֹת:
(1) כי עבדך ערב את הנער FOR THY SERVANT BECAME SURETY FOR THE LAD — Should you ask why I enter into the contest (champion his cause) more strongly than my other brothers — then I tell you: I have more to lose; they all stand outside the matter (are less concerned with it than I am), but I have placed myself under a firm bond to be an outcast in both worlds.

According to Rashi, Judah will be an outcast in Two Worlds if Benjamin is kept as a slave instead of him. What two worlds?

(ח) וַיֹּ֨אמֶר יְהוּדָ֜ה אֶל־יִשְׂרָאֵ֣ל אָבִ֗יו שִׁלְחָ֥ה הַנַּ֛עַר אִתִּ֖י וְנָק֣וּמָה וְנֵלֵ֑כָה וְנִֽחְיֶה֙ וְלֹ֣א נָמ֔וּת גַּם־אֲנַ֥חְנוּ גַם־אַתָּ֖ה גַּם־טַפֵּֽנוּ׃ (ט) אָֽנֹכִי֙ אֶֽעֶרְבֶ֔נּוּ מִיָּדִ֖י תְּבַקְשֶׁ֑נּוּ אִם־לֹ֨א הֲבִיאֹתִ֤יו אֵלֶ֙יךָ֙ וְהִצַּגְתִּ֣יו לְפָנֶ֔יךָ וְחָטָ֥אתִֽי לְךָ֖ כָּל־הַיָּמִֽים׃
(8) Then Judah said to his father Israel, “Send the boy in my care, and let us be on our way, that we may live and not die—you and we and our children. (9) I myself will be surety for him; you may hold me responsible: if I do not bring him back to you and set him before you, I shall stand guilty before you forever.
(ב) וחטאתי לך כל הימים. לָעוֹלָם הַבָּא:
(2) וחטאתי לך כל הימים THEN SHALL I HAVE SINNED AGAINST THEE ALL THE DAYS — also in the world to come (Genesis Rabbah 91:10).

(ה) מַזְכִּירִין יְצִיאַת מִצְרַיִם בַּלֵּילוֹת. אָמַר רַבִּי אֶלְעָזָר בֶּן עֲזַרְיָה, הֲרֵי אֲנִי כְּבֶן שִׁבְעִים שָׁנָה, וְלֹא זָכִיתִי שֶׁתֵּאָמֵר יְצִיאַת מִצְרַיִם בַּלֵּילוֹת, עַד שֶׁדְּרָשָׁהּ בֶּן זוֹמָא, שֶׁנֶּאֱמַר (דברים טז) לְמַעַן תִּזְכֹּר אֶת יוֹם צֵאתְךָ מֵאֶרֶץ מִצְרַיִם כֹּל יְמֵי חַיֶּיךָ. יְמֵי חַיֶּיךָ, הַיָּמִים. כֹּל יְמֵי חַיֶּיךָ, הַלֵּילוֹת. וַחֲכָמִים אוֹמְרִים, יְמֵי חַיֶּיךָ, הָעוֹלָם הַזֶּה. כֹּל יְמֵי חַיֶּיךָ, לְהָבִיא לִימוֹת הַמָּשִׁיחַ:

(5) One must mention the exodus from Egypt at night. Rabbi Elazar ben Azaryah said: "Behold, I am like a seventy-year-old man, yet I could not win [the argument against the other sages] having the exodus from Egypt recited at night, until Ben Zoma derived it [from a Biblical source]." "[He derived it as follows:] It says (Deut. 16:3), 'In order that you may remember the day when you left Egypt for all the days of your life.'" "Now, 'days of your life' means the days; 'All the days of your life' [includes also] the nights." But the Sages say: "Days of your life" means the present world; "All the days of your life" includes also the era of Mashiach.

Shlomo Yitzchaki (Hebrew: רבי שלמה יצחקי‬‎) 22 February 1040 – 13 July 1105, today generally known by the acronym Rashi (Hebrew: רש"י‬, RAbbi SHlomo Itzhaki), was a medieval French rabbi and author of a comprehensive commentary on the Talmud and commentary on the Tanakh. Acclaimed for his ability to present the basic meaning of the text in a concise and lucid fashion, Rashi appeals to both learned scholars and beginner students, and his works remain a centerpiece of contemporary Jewish study.

What is the sin/violation would have made Judah an outcast in two worlds?

What are other ways we might look at 'the world to come' or 'the Days of Moshiach' besides an afterlife?

How might we become an outcast in two world's today? (whether we believe in a 'world to come' or not)
