The foundational Talmudic debate on whether the Ten Tribes will return in the future: R. Akiva holds they will not, while R. Eliezer holds they will, basing his view on Isaiah's prophecy that God will gather the dispersed of Israel. The Maharal's analysis builds directly on this sugya.
מַתְנִי׳ עֲשֶׂרֶת הַשְּׁבָטִים אֵינָן עֲתִידִין לַחֲזוֹר, שֶׁנֶּאֱמַר: ״וַיַּשְׁלִכֵם אֶל אֶרֶץ אַחֶרֶת כַּיּוֹם הַזֶּה״. מָה הַיּוֹם הוֹלֵךְ וְאֵינוֹ חוֹזֵר – אַף הֵם הוֹלְכִים וְאֵינָן חוֹזְרִים, דִּבְרֵי רַבִּי עֲקִיבָא. רַבִּי אֱלִיעֶזֶר אוֹמֵר: ״כַּיּוֹם הַזֶּה״ – מָה יוֹם מַאֲפִיל וּמֵאִיר, אַף עֲשֶׂרֶת הַשְּׁבָטִים שֶׁאֲפֵילָה לָהֶן כָּךְ עֲתִידָה לְהָאִיר לָהֶם. גְּמָ׳ תָּנוּ רַבָּנַן: עֲשֶׂרֶת הַשְּׁבָטִים אֵין לָהֶם חֵלֶק לָעוֹלָם הַבָּא, שֶׁנֶּאֱמַר: ״וַיִּתְּשֵׁם ה׳ מֵעַל אַדְמָתָם בְּאַף וּבְחֵמָה וּבְקֶצֶף גָּדוֹל״. ״וַיִּתְּשֵׁם ה׳ מֵעַל אַדְמָתָם״ – בְּעוֹלָם הַזֶּה, ״וַיַּשְׁלִכֵם אֶל אֶרֶץ אַחֶרֶת״ – לָעוֹלָם הַבָּא, דִּבְרֵי רַבִּי עֲקִיבָא. רַבִּי שִׁמְעוֹן בֶּן יְהוּדָה אִישׁ כְּפַר עַכּוֹ אוֹמֵר מִשּׁוּם רַבִּי שִׁמְעוֹן: אִם מַעֲשֵׂיהֶם כַּיּוֹם הַזֶּה – אֵינָן חוֹזְרִין, וְאִם לָאו – חוֹזְרִין. רַבִּי אוֹמֵר: בָּאִים הֵם לָעוֹלָם הַבָּא, שֶׁנֶּאֱמַר: ״בַּיּוֹם הַהוּא יִתָּקַע בְּשׁוֹפָר גָּדוֹל וְגוֹ׳״. אָמַר רַבָּה בַּר בַּר חָנָה אָמַר רַבִּי יוֹחָנָן: שַׁבְקַהּ רַבִּי עֲקִיבָא לַחֲסִידוּתֵיהּ, שֶׁנֶּאֱמַר: ״הָלֹךְ וְקָרָאתָ אֶת הַדְּבָרִים הָאֵלֶּה צָפוֹנָה וְאָמַרְתָּ שׁוּבָה מְשֻׁבָה יִשְׂרָאֵל נְאֻם ה׳ לוֹא אַפִּיל פָּנַי בָּכֶם כִּי חָסִיד אֲנִי נְאֻם ה׳ לֹא אֶטּוֹר לְעוֹלָם״.
MISHNA: The ten tribes are not destined to return to Eretz Yisrael, even during the messianic era, as it is stated: “And He cast them into another land, as it is this day” (Deuteronomy 29:27). Just as the day passes never to return, so too, the ten tribes go into exile and do not return; this is the statement of Rabbi Akiva. Rabbi Eliezer says: “As it is this day,” meaning just as the day darkens and then the sky brightens the next day, with regard to the ten tribes as well, although it is dark for them now, so it is destined to brighten for them. GEMARA: The Sages taught in a baraita (Tosefta 13:12): The ten tribes have no share in the World-to-Come, as it is stated: “And the Lord rooted them out of their land in anger, and in wrath, and in great indignation; and He cast them into another land, as it is this day” (Deuteronomy 29:27). “And the Lord rooted them out of their land” indicates in this world; “and cast them into another land” indicates for the World-to-Come; this is the statement of Rabbi Akiva. Rabbi Shimon ben Yehuda of the village of Akko says in the name of Rabbi Shimon: If their actions continue to be “as it is this day” and they continue to sin, they do not return to Eretz Yisrael. And if not, and they repent, they return to Eretz Yisrael. Rabbi Yehuda HaNasi says: The members of the ten tribes come to the World-to-Come, as it is stated: “And it shall come to pass on that day, that a great shofar will be sounded, and they shall come who were lost in the land of Assyria and who were dispersed in the land of Egypt, and they shall worship the Lord at the holy mountain in Jerusalem” (Isaiah 27:13). Rabba bar bar Ḥana says that Rabbi Yoḥanan says: Here too, Rabbi Akiva abandoned his piety and uncharacteristically interpreted the verses harshly, as it is stated with regard to the ten tribes: “Go and proclaim these words toward the north, and say: Return you faithless Israel, says the Lord; I will not frown upon you; for I am merciful, says the Lord, and I will not bear a grudge forever” (Jeremiah 3:12). The prophet prophesies about the return of the ten tribes to Eretz Yisrael.
