The Talmud discusses which empire will prevail in the end of days — Rome or Persia — and connects these nations to the biblical genealogies, touching on the broader framework of world powers and their relationship to the children of Shem and Yishmael.
וּפָרְסָאֵי מְנָא לַן דְּמִיֶּפֶת קָאָתוּ, דִּכְתִיב: ״בְּנֵי יֶפֶת גּוֹמֶר וּמָגוֹג וּמָדַי וְיָוָן וְתוּבָל וּמֶשֶׁךְ וְתִירָס״. גּוֹמֶר — זֶה גֶּרְמַמְיָא, מָגוֹג — זוֹ קַנְדִּיָּא, מָדַי — זוֹ מַקֵדוֹנְיָא, יָוָן — כְּמַשְׁמָעוֹ, תּוּבָל — זֶה בֵּית אוּנַיְיקִי, מֶשֶׁךְ — זוֹ מוּסְיָא, תִּירָס, פְּלִיגִי בַּהּ רַבִּי סִימַאי וְרַבָּנַן, וְאָמְרִי לַהּ רַבִּי סִימוֹן וְרַבָּנַן, חַד אָמַר: זוֹ בֵּית תְּרַיְיקִי, וְחַד אָמַר: זוֹ פָּרַס. תָּנֵי רַב יוֹסֵף: תִּירָס — זוֹ פָּרַס. אָמַר רַבָּה בַּר בַּר חָנָה אָמַר רַבִּי יוֹחָנָן מִשּׁוּם רַבִּי יְהוּדָה בְּרַבִּי אִלְעַאי: עֲתִידָה רוֹמִי שֶׁתִּפּוֹל בְּיַד פָּרַס, קַל וָחוֹמֶר: וּמָה מִקְדָּשׁ רִאשׁוֹן שֶׁבְּנָאוּהוּ בְּנֵי שֵׁם וְהֶחְרִיבוּהוּ כַּשְׂדִּיִּים — נָפְלוּ כַּשְׂדִּיִּים בְּיַד פָּרְסִיִּים. מִקְדָּשׁ שֵׁנִי שֶׁבְּנָאוּהוּ פָּרְסִיִּים וְהֶחְרִיבוּהוּ רוֹמִיִּים — אֵינוֹ דִּין שֶׁיִּפְּלוּ רוֹמִיִּים בְּיַד פָּרְסִיִּים?
§ The Gemara asks: From where do we derive that the Persians descend from Japheth? The Gemara answers: As it is written: “The sons of Japheth were Gomer and Magog and Madai and Javan and Tuval and Meshech and Tiras” (Genesis 10:2). The Gemara explains: Gomer, that is Germamya; Magog, that is Kandiya; Madai, that is Macedonia; Javan, in accordance with its plain meaning, Greece; Tuval, that is the nation called Beit Unaiki; Meshech, that is Musya. With regard to Tiras, Rabbi Simai and the Rabbis disagree, and some say the dispute is between Rabbi Simon and the Rabbis: One said: That is Beit Teraiki, and one said: That is Persia. According to that approach, Persia is listed among the descendants of Japheth. Rav Yosef taught: Tiras is Persia. Similarly, Rabba bar bar Ḥana said that Rabbi Yoḥanan said in the name of Rabbi Yehuda, son of Rabbi Elai: Rome is destined to fall into the hands of Persia. This is derived by means of an a fortiori inference: Just as the First Temple, that the descendants of Shem built it and the Chaldeans destroyed it, and in turn the Chaldeans, ruled by Belshazzar, fell to Persians, ruled by Darius the Mede and his son-in-law Cyrus the Persian; the Second Temple, that the Persians built it and the Romans destroyed it, is it not right that the Romans will fall into the hands of the Persians?
