Who is the Messiah? Historical exploration of the Jewish concept of the Messiah
אֶרְאֶ֙נּוּ֙ וְלֹ֣א עַתָּ֔ה אֲשׁוּרֶ֖נּוּ וְלֹ֣א קָר֑וֹב דָּרַ֨ךְ כּוֹכָ֜ב מִֽיַּעֲקֹ֗ב וְקָ֥ם שֵׁ֙בֶט֙ מִיִּשְׂרָאֵ֔ל וּמָחַץ֙ פַּאֲתֵ֣י מוֹאָ֔ב וְקַרְקַ֖ר כָּל־בְּנֵי־שֵֽׁת׃
What I see for them is not yet, What I behold will not be soon: A star rises from Jacob, A scepter comes forth from Israel; It smashes the brow of Moab, The foundation of all children of Seth.

Pre-exile Jewish eschatology (8th–6th cent. BCE)

The roots of Jewish eschatology are to be found in the pre-exile prophets, including Isaiah and Jeremiah, and the exile prophets Ezekiel and Deutero-Isaiah.[web 4] The main tenets of Jewish eschatology are the following, in no particular order, elaborated in the books of Isaiah, Jeremiah and Ezekiel:[web 5]

אָמַר רָבָא: בְּשָׁעָה שֶׁמַּכְנִיסִין אָדָם לְדִין, אוֹמְרִים לוֹ: נָשָׂאתָ וְנָתַתָּ בָּאֱמוּנָה? קָבַעְתָּ עִתִּים לַתּוֹרָה? עָסַקְתָּ בִּפְרִיָּה וּרְבִיָּה? צָפִיתָ לִישׁוּעָה? פִּלְפַּלְתָּ בְּחׇכְמָה? הֵבַנְתָּ דָּבָר מִתּוֹךְ דָּבָר? וַאֲפִילּוּ הָכִי, אִי יִרְאַת ה׳ הִיא אוֹצָרוֹ — אִין, אִי לָא — לָא. מָשָׁל לְאָדָם שֶׁאָמַר לִשְׁלוּחוֹ: הַעֲלֵה לִי כּוֹר חִיטִּין לָעֲלִיָּיה. הָלַךְ וְהֶעֱלָה לוֹ. אָמַר לוֹ: עֵירַבְתָּ לִי בָּהֶן קַב חוֹמְטוֹן? אָמַר לוֹ: לָאו. אָמַר לוֹ: מוּטָב אִם לֹא הֶעֱלֵיתָה.
When a man is brought before the [heavenly] court he is asked: "Were you trustworthy in business? Did you set time for Torah [study]? Did you try to have kids? Did you hope for the Messiah? Did you argue intelligently? Did you understand things based on other things?"

The Mishneh Torah, is a code of Rabbinic Jewish religious law (Halakha) authored by Maimonides (Rabbi Moshe ben Maimon). The Mishneh Torah was compiled between 1170 and 1180 CE (4930 and 4940 AM), while Maimonides was living in Egypt.

Mishneh Torah consists of fourteen books, subdivided into sections, chapters, and paragraphs. It is the only Medieval-era work that details all of Jewish observance, including those laws that are only applicable when the Temple in Jerusalem is in existence, and remains an important work in Judaism.

Who is the Messiah?
וְאִם יַעֲמֹד מֶלֶךְ מִבֵּית דָּוִד הוֹגֶה בַּתּוֹרָה וְעוֹסֵק בְּמִצְוֹת כְּדָוִד אָבִיו. כְּפִי תּוֹרָה שֶׁבִּכְתָב וְשֶׁבְּעַל פֶּה. וְיָכֹף כָּל יִשְׂרָאֵל לֵילֵךְ בָּהּ וּלְחַזֵּק בִּדְקָהּ. וְיִלָּחֵם מִלְחֲמוֹת ה'. הֲרֵי זֶה בְּחֶזְקַת שֶׁהוּא מָשִׁיחַ. (אִם עָשָׂה וְהִצְלִיחַ וּבָנָה מִקְדָּשׁ בִּמְקוֹמוֹ וְקִבֵּץ נִדְחֵי יִשְׂרָאֵל הֲרֵי זֶה מָשִׁיחַ בְּוַדַּאי. וִיתַקֵּן אֶת הָעוֹלָם כֻּלּוֹ לַעֲבֹד אֶת ה' בְּיַחַד שֶׁנֶּאֱמַר כִּי אָז אֶהְפֹּךְ אֶל עַמִּים שָׂפָה בְרוּרָה לִקְרֹא כֻלָּם בְּשֵׁם ה' וּלְעָבְדוֹ שְׁכֶם אֶחָד):

Now, if a king should arise from the House of David who is versed in Torah and engages in Commandments, as did David his forefather, in accordance with both the Written and the Oral Torahs, and he enjoins all of Israel to follow in its ways and encourages them to repair its breaches, and he fights the Wars of G-d128I.e. he defends Israel., then he may be presumed to be the Messiah. If he succeeds in his efforts and defeats the enemies around and builds the Sanctuary in its proper place and gathers the dispersed of Israel, he is definitely the Messiah.

וְאִם לֹא הִצְלִיחַ עַד כֹּה, אוֹ נֶהֱרָג, בְּיָדוּעַ שֶׁאֵינוֹ זֶה שֶׁהִבְטִיחָה עָלָיו תּוֹרָה, וַהֲרֵי הוּא כְּכָל מַלְכֵי בֵּית דָּוִד הַשְּׁלֵמִים הַכְּשֵׁרִים שֶׁמֵּתוּ. וְלֹא הֶעֱמִידוֹ הַקָּדוֹשׁ בָּרוּךְ הוּא אֶלָּא לְנַסּוֹת בּוֹ רַבִּים, שֶׁנֶּאֱמַר "וּמִן הַמַּשְׂכִּילִים יִכָּשְׁלוּ לִצְרוֹף בָּהֶן וּלְבָרֵר וְלַלְבֵּן עַד עֵת קֵץ כִּי עוֹד לַמּוֹעֵד".
But, if he does not succeed in these matters or is killed, we will know that he was not the one Torah has promised. He is (merely to be considered) like all the (other) exemplary and qualified kings of the House of David who have died. G-d set him up only to try the masses, as it says, “And some of the wise will stumble, to refine among them and to purify and to make white, even to the time of the end, for it is yet for the time appointed” (Daniel 11:35).
וּכְשֶׁיַּעֲמוֹד הַמֶּלֶךְ הַמָּשִׁיחַ בֶּאֱמֶת, וְיַצְלִיחַ וְיָרוּם וְיִינָשֵׂא, מִיַּד הֵם כּוּלָן חוֹזְרִין וְיוֹדְעִים שֶׁשֶּׁקֶר נָחֲלוּ אֲבוֹתֵיהֶם, וְשֶׁנְּבִיאֵיהֶם וַאֲבוֹתֵיהֶם הִטְעוּם.
But when the true King Messiah will rise and succeed, and he will be lifted up and raised aloft, they all will immediately return and will know that their fathers left them an erroneous legacy, and their fathers and prophets led them astray.
What will happen when the Messiah comes?
אַל יַעֲלֶה עַל הַלֵּב שֶׁבִּימוֹת הַמָּשִׁיחַ יִבָּטֵל דּבָר מִמִּנְהָגוֹ שֶׁל עוֹלָם. אוֹ יִהְיֶה שָׁם חִדּוּשׁ בְּמַעֲשֵׂה בְּרֵאשִׁית. אֶלָּא עוֹלָם כְּמִנְהָגוֹ נוֹהֵג. וְזֶה שֶׁנֶּאֱמַר בִּישַׁעְיָה (ישעיה יא, ו) "וְגָר זְאֵב עִם כֶּבֶשׂ וְנָמֵר עִם גְּדִי יִרְבָּץ" מָשָׁל וְחִידָה. עִנְיַן הַדָּבָר שֶׁיִּהְיוּ יִשְׂרָאֵל יוֹשְׁבִין לָבֶטַח עִם רִשְׁעֵי עַכּוּ''ם הַמְשׁוּלִים כִּזְאֵב וְנָמֵר. שֶׁנֶּאֱמַר (ירמיה ה, ו) "זְאֵב עֲרָבוֹת יְשָׁדְדֵם וְנָמֵר שֹׁקֵד עַל עָרֵיהֶם". וְיַחְזְרוּ כֻּלָּם לְדַת הָאֱמֶת. וְלֹא יִגְזְלוּ וְלֹא יַשְׁחִיתוּ. אֶלָּא יֹאכְלוּ דָּבָר הַמֻּתָּר בְּנַחַת עִם יִשְׂרָאֵל. שֶׁנֶּאֱמַר (ישעיה יא, ז) "וְאַרְיֵה כַּבָּקָר יֹאכַל תֶּבֶן". וְכֵן כָּל כַּיּוֹצֵא בְּאֵלּוּ הַדְּבָרִים בְּעִנְיַן הַמָּשִׁיחַ הֵם מְשָׁלִים. וּבִימוֹת הַמֶּלֶךְ הַמָּשִׁיחַ יִוָּדַע לַכּל לְאֵי זֶה דָּבָר הָיָה מָשָׁל. וּמָה עִנְיָן רָמְזוּ בָּהֶן:

It should not occur to you that during the days of the Messiah a single thing from the “ways of the world”135I.e. Nature. will be canceled nor will there be something novel in the Creation. Rather, the world will continue in its customary way. Now, that which is said in Isaiah, “And the wolf will live with the sheep and the leopard shall lie down with the kid” (Isaiah 11:6) is a parable and riddle. The substance of the matter is that Israel will dwell in safety with the wicked of the world who are compared to wolves and tigers, as it says, “a wolf of the deserts spoil them, a leopard watches over their cities” (Jeremiah 5:6). But, they will all return to the true religion and they will not steal and not destroy. Rather, they will eat of the permissible foods comfortably136I.e. in peace. like Israel, as it says, “and the lion will eat straw as does the ox” (Isaiah 11:7). And so similar matters written about the Messiah are parables. In the days of the King Messiah everyone will understand these parables and to what these matters were compared and to what was hinted.

What is the difference between the period of the Messiah and Olam Habah?
מַרְגְּלָא בְּפוּמֵּיהּ דְּרַב: לֹא כָּעוֹלָם הַזֶּה הָעוֹלָם הַבָּא. הָעוֹלָם הַבָּא אֵין בּוֹ לֹא אֲכִילָה וְלֹא שְׁתִיָּהּ וְלֹא פְּרִיָּה וּרְבִיָּה וְלֹא מַשָּׂא וּמַתָּן וְלֹא קִנְאָה וְלֹא שִׂנְאָה וְלֹא תַּחֲרוּת, אֶלָּא צַדִּיקִים יוֹשְׁבִין וְעַטְרוֹתֵיהֶם בְּרָאשֵׁיהֶם וְנֶהֱנִים מִזִּיו הַשְּׁכִינָה, שֶׁנֶּאֱמַר: ״וַיֶּחֱזוּ אֶת הָאֱלֹהִים וַיֹּאכְלוּ וַיִּשְׁתּוּ״.

Rav was wont to say:
The World-to-Come is not like this world.
In the World-to-Come there is no eating, no drinking,
no procreation, no business negotiations,
no jealousy, no hatred, and no competition.
Rather, the righteous sit with their crowns upon their heads, enjoying the splendor of the Divine Presence, as it is stated:
“And they beheld God, and they ate and drank” (Exodus 24:11), meaning that beholding God’s countenance is tantamount to eating and drinking.

וְאָמַר רַבִּי חִיָּיא בַּר אַבָּא אָמַר רַבִּי יוֹחָנָן: כׇּל הַנְּבִיאִים כּוּלָּן לֹא נִתְנַבְּאוּ אֶלָּא לִימוֹת הַמָּשִׁיחַ, אֲבָל לְעוֹלָם הַבָּא, ״עַיִן לֹא רָאָתָה אֱלֹהִים זוּלָתְךָ״.
And Rabbi Ḥiyya bar Abba said that Rabbi Yoḥanan said: All the prophets only prophesied with regard to the change in world order in the end of days with regard to the days of the Messiah. However, with regard to the World-to-Come, which exists on a higher level, it is stated: “No eye has seen it, God, aside from You.”
וּפְלִיגָא דִּשְׁמוּאֵל, דְּאָמַר שְׁמוּאֵל: אֵין בֵּין הָעוֹלָם הַזֶּה לִימוֹת הַמָּשִׁיחַ אֶלָּא שִׁעְבּוּד מַלְכוּיוֹת בִּלְבַד. שֶׁנֶּאֱמַר: ״כִּי לֹא יֶחְדַּל אֶבְיוֹן מִקֶּרֶב הָאָרֶץ״.
And the Gemara notes that this statement disagrees with the opinion of Shmuel, as Shmuel said: The only difference between this world and the days of the Messiah is with regard to servitude to foreign kingdoms alone. While in the days of the Messiah, Israel will be independent and free from enslavement to foreign powers, the world order will remain otherwise unchanged, as it is stated: “For the poor shall not cease from the land” (Deuteronomy 15:11), which indicates that the ways of the world are set and unchanging.

What will resurrection be like?

Leah Leila Bronner, Journey to Heaven

...[the rabbis speculate] about the state in which the dead will arise. If there is to be actual physical resurrection, what shape will bodies be in? It is concluded that bodies are resurrected in the state in which they died, though it is possible for healing to take place after that. For example, a person identified as Queen Cleopatra asks Rabbi Meir whether the dead will be naked or clothed. Rabbi Meir answers that in the same way that wheat rises "clothed" [in its outer covering, the chaff], so will the dead (Sanhedrin 90b). Similarly, Resh Lakish and Rava both allege that people will be revived with the defects they had when they died, but will subsequently be healed. (Sanhedrin 91a)

Maimonides' Treatise on Resurrection (c. 1191)

https://books.google.com/books?id=tKYOW4_RdH0C&q=%22days+of+the+messiah%22#v=snippet&q=%22days%20of%20the%20messiah%22&f=false
iv. 21-24:
the resurrection of the dead... is widely known and accepted among our people... [and] means that the soul will return to its body after its separation... it cannot be interpreted allegorically... [The Talmud implies] that those individuals whose souls return to their bodies (after death) will eat and drink... and sire children and die after an extremely long life like the life which will exist during the days of the Messiah... [however] in the world to come souls without bodies will exist like angels.

[Written in response to accusations in Yemen and Iraq that Maimonides denied bodily resurrection.]

When Will The Messiah Come?
אמר ליה אימת אתי משיח אמר ליה זיל שייליה לדידיה והיכא יתיב אפיתחא דקרתא ומאי סימניה יתיב ביני עניי סובלי חלאים וכולן שרו ואסירי בחד זימנא איהו שרי חד ואסיר חד אמר דילמא מבעינא דלא איעכב

Rabbi Yehoshua ben Levi said to Elijah: When will the Messiah come? Elijah said to him: Go ask him. Rabbi Yehoshua ben Levi asked: And where is he sitting? Elijah said to him: At the entrance of the city of Rome. Rabbi Yehoshua ben Levi asked him: And what is his identifying sign by means of which I can recognize him? Elijah answered: He sits among the poor who suffer from illnesses. And all of them untie their bandages and tie them all at once, but the Messiah unties one bandage and ties one at a time. He says: Perhaps I will be needed to serve to bring about the redemption. Therefore, I will never tie more than one bandage, so that I will not be delayed.

אזל לגביה אמר ליה שלום עליך רבי ומורי אמר ליה שלום עליך בר ליואי א"ל לאימת אתי מר א"ל היום אתא לגבי אליהו א"ל מאי אמר לך א"ל שלום עליך בר ליואי א"ל אבטחך לך ולאבוך לעלמא דאתי א"ל שקורי קא שקר בי דאמר לי היום אתינא ולא אתא א"ל הכי אמר לך (תהלים צה, ז) היום אם בקולו תשמעו
Rabbi Yehoshua ben Levi went to the Messiah. He said to the Messiah: Greetings to you, my rabbi and my teacher. The Messiah said to him: Greetings to you, bar Leva’i. Rabbi Yehoshua ben Levi said to him: When will the Master come? The Messiah said to him: Today. Sometime later, Rabbi Yehoshua ben Levi came to Elijah. Elijah said to him: What did the Messiah say to you? He said to Elijah that the Messiah said: Greetings [shalom] to you, bar Leva’i. Elijah said to him: He thereby guaranteed that you and your father will enter the World-to-Come, as he greeted you with shalom. Rabbi Yehoshua ben Levi said to Elijah: The Messiah lied to me, as he said to me: I am coming today, and he did not come. Elijah said to him that this is what he said to you: He said that he will come “today, if you will listen to his voice” (Psalms 95:7).
שאלו תלמידיו את רבי יוסי בן קיסמא אימתי בן דוד בא אמר מתיירא אני שמא תבקשו ממני אות אמרו לו אין אנו מבקשין ממך אות
§ Rabbi Yosei ben Kisma’s students asked him: When will the son of David come? Rabbi Yosei ben Kisma said: I am hesitant to answer you, lest you request from me a sign to corroborate my statement. They said to him: We are not asking you for a sign.
א"ל לכשיפול השער הזה ויבנה ויפול ויבנה ויפול ואין מספיקין לבנותו עד שבן דוד בא אמרו לו רבינו תן לנו אות אמר להם ולא כך אמרתם לי שאין אתם מבקשין ממני אות
Rabbi Yosei ben Kisma said to them: You will see when this existing gate of Rome falls and will be rebuilt, and will fall a second time and will be rebuilt, and will fall a third time. And they will not manage to rebuild it until the son of David comes. The students said to him: Our rabbi, give us a sign. Rabbi Yosei ben Kisma said to them: But didn’t you say to me that you are not asking me for a sign?
ואמר רבי יוחנן אין בן דוד בא אלא בדור שכולו זכאי או כולו חייב בדור שכולו זכאי דכתיב (ישעיהו ס, כא) ועמך כולם צדיקים לעולם יירשו ארץ בדור שכולו חייב דכתיב (ישעיהו נט, טז) וירא כי אין איש וישתומם כי אין מפגיע וכתיב (ישעיהו מח, יא) למעני אעשה

And Rabbi Yoḥanan says: The son of David will come only in a generation that is entirely innocent, in which case they will be deserving of redemption, or in a generation that is entirely guilty, in which case there will be no alternative to redemption. He may come in a generation that is entirely innocent, as it is written: “And your people also shall be all righteous; they shall inherit the land forever” (Isaiah 60:21). He may come in a generation that is entirely guilty, as it is written: “And He saw that there was no man, and was astonished that there was no intercessor; therefore His arm brought salvation to Him, and His righteousness, it sustained Him” (Isaiah 59:16). And it is written: “For My own sake, for My own sake will I do it; for how should it be profaned? And My glory I will not give it to another” (Isaiah 48:11).

בעתה וכתיב אחישנה זכו אחישנה לא זכו בעתה

If they merit redemption through repentance and good deeds I will hasten the coming of the Messiah. If they do not merit redemption, the coming of the Messiah will be in its designated time.

אם היתה נטיעה בתוך ידך ויאמרו לך הרי לך המשיח. בוא ונטע את הנטיעה (ואח”כ צא והקביל).

Midrash Avot Derabbi Natan, Version B, Chapter 31

If you had a sapling in your hand and were told that the Messiah had come, first plant the sapling [and then go out to greet the Messiah].

Jewish Literacy, Joseph Telushkin, page 600-601

An old Jewish story tells of a Russian Jew who was paid a ruble a month by the community council to stand at the outskirts of town so that he could be the first person to greet the Messiah upon his arrival. When a friend said to him, "But the pay is so low," the man replied: "True, but the job is permanent."

Why do we want the Messiah to come?

Jonathan Sacks, "Future Tense," The Jewish Chronicle, April 1, 2008

Judaism is the only civilization whose golden age is in the future: the messianic age, the age of peace when ‘nation will not lift up sword against nation’ and ‘the Lord shall be one and His name One’. This ultimately was the dividing line between Judaism and Christianity. To be a Jew is to reply to the question ‘Has the messiah come?’ with the words ‘Not yet.’ In the fine phrase of Harold Fisch, the Jewish narrative is ‘the unappeased memory of a future still to be fulfilled’. Why? What does this tell us about Judaism?

At the heart of Judaism is a belief so fundamental to Western civilization that we take it for granted, yet it is anything but self-evident. It has been challenged many times, rarely more so than today. It is the belief in human freedom. We are what we choose to be. Society is what we choose to make it. The future is open. There is nothing inevitable in the affairs of humankind...

Judaism is a religion of details, but we miss the point if we do not sometimes step back and see the larger picture. To be a Jew is to be an agent of hope in a world serially threatened by despair. Every ritual, every mitzvah, every syllable of the Jewish story, every element of Jewish law, is a protest against escapism, resignation or the blind acceptance of fate. Judaism is a sustained struggle, the greatest ever known, against the world that is, in the name of the world that could be, should be, but is not yet. There is no more challenging vocation. Throughout history, when human beings have sought hope they have found it in the Jewish story. Judaism is the religion, and Israel the home, of hope.

האמונה בביאת המשיח מחוייבת על כל בעל תורת משה, כמו שבארנו בפרק כ״ג מהמאמר הראשון, וזה כי לפי שבא בתורה מפורש החיוב להאמין בדברי הנביא, שנאמר אליו תשמעון, והנביאים נבאו בביאת המשיח, הוא מבואר שכל מי שאינו מאמין בביאת המשיח הוא כופר בדברי הנביאים ועובר על מצות עשה, אבל מכל מקום אין האמנת ביאת המשיח עיקר שתבטל התורה בכללה אם לא יאמינהו האדם.
Every adherent of the Law of Moses is obliged to believe in the coming of the Messiah, as we explained above. The Torah expressly commands us to believe the words of the prophet: “Unto him ye shall hearken.” But the prophets announced the coming of the Messiah, hence it is clear that any one who does not believe in the coming of the Messiah denies the words of the prophets and transgresses a mandatory precept. But the belief in the coming of the Messiah is not a fundamental principle, denial of which would nullify the entire Torah.

To believe in the coming of Mashiach and to await it are two separate concepts. “To believe” is a doctrinal affirmation as for any other part of the Torah: affirming the principle of Mashiach who will come eventually, whenever that may be. “To await” means an active and eager anticipation of the redemption, that it occur speedily: “I await him every day…,” literally.

If he does come, what will he do?

וְהָיָ֣ה ׀ בַּיּ֣וֹם הַה֗וּא יוֹסִ֨יף אֲדֹנָ֤י ׀ שֵׁנִית֙ יָד֔וֹ לִקְנ֖וֹת אֶת־שְׁאָ֣ר עַמּ֑וֹ אֲשֶׁ֣ר יִשָּׁאֵר֩ מֵאַשּׁ֨וּר וּמִמִּצְרַ֜יִם וּמִפַּתְר֣וֹס וּמִכּ֗וּשׁ וּמֵעֵילָ֤ם וּמִשִּׁנְעָר֙ וּמֵ֣חֲמָ֔ת וּמֵאִיֵּ֖י הַיָּֽם׃
In that day, my Lord will apply His hand again to redeeming the other part of His people from Assyria—as also from Egypt, Pathros, Nubia, Elam, Shinar, Hamath, and the coastlands.

והתועלת הגדול אשר תהיה באותם הימים הוא שננוח משעבוד מלכיות שהוא מונע אותנו מעשיית המצות כולם, ותרבה החכמה כמו שנאמר ”כִּ י מָ לְ אָ ה הָ אָ רֶ ץ דּעָה ]אֶת ה‘ כַּמַּיִם לַיָּם מְ כַסִּים[“, וישבתו המלחמות כמו שנאמר ”]וְ כִ תְּ תוּ חַ רְ בוֹתָ ם לְ אִ תִּ ים וַ חֲ נִ יתוֹתֵ יהֶ ם לְ מַ זְ מֵ רוֹת[ לֹא יִ שּ ָׂ א גוֹי אֶ ל גּ וֹי חֶ רֶ ב ]וְ לֹא יִ לְ מְ דוּ עוֹד מִ לְ חָ מָ ה[“, ויהיה נמצא בימים ההם שלימות רב ונזכה בו לחיי העולם הבא.

Rambam on the Mishnah, Sanhedrin 10

The great benefit which will be in those days [of the Mashiach] is that we will rest from our subjugation to the non-Jewish governments, which is what prevents us from fulfilling all the mitzvot. Wisdom will increase... War will cease, as the verse states, “They shall beat their swords into ploughshares and their spears into pruning hooks. Nation will not lift up sword against nation, and neither shall they learn war any more”. In those days there will be ultimate perfection and we will merit the life of the World to Come.

הַמֶּלֶךְ הַמָּשִׁיחַ עָתִיד לַעֲמֹד וּלְהַחְזִיר מַלכוּת דָּוִד לְיָשְׁנָהּ לַמֶּמְשָׁלָה הָרִאשׁוֹנָה. וּבוֹנֶה הַמִּקְדָּשׁ וּמְקַבֵּץ נִדְחֵי יִשְׂרָאֵל. וְחוֹזְרִין כָּל הַמִּשְׁפָּטִים בְּיָמָיו כְּשֶׁהָיוּ מִקֹּדֶם. מַקְרִיבִין קָרְבָּנוֹת. וְעוֹשִׂין שְׁמִטִּין וְיוֹבְלוֹת כְּכָל מִצְוָתָן הָאֲמוּרָה בַּתּוֹרָה. וְכָל מִי שֶׁאֵינוֹ מַאֲמִין בּוֹ. אוֹ מִי שֶׁאֵינוֹ מְחַכֶּה לְבִיאָתוֹ. לֹא בִּשְׁאָר נְבִיאִים בִּלְבַד הוּא כּוֹפֵר. אֶלָּא בַּתּוֹרָה וּבְמשֶׁה רַבֵּנוּ.

The King Messiah will arise and re-establish the monarchy of David as it was in former times. He will build the Sanctuary and gather in the dispersed of Israel. All the earlier statutes will be restored as they once were. Sacrifices will be offered, the Sabbatical and Jubilee years will be observed, as commanded in the Torah. Anyone who does not believe in him or one who does not anticipate his coming not only denies the Prophets, but also the Torah and Moses our Teacher.

Sounds good. Anything else? Anything mystical?

וּבְאוֹתוֹ הַזְּמַן לֹא יִהְיֶה שָׁם לֹא רָעָב וְלֹא מִלְחָמָה. וְלֹא קִנְאָה וְתַחֲרוּת. שֶׁהַטּוֹבָה תִּהְיֶה מֻשְׁפַּעַת הַרְבֵּה. וְכָל הַמַּעֲדַנִּים מְצוּיִין כֶּעָפָר. וְלֹא יִהְיֶה עֵסֶק כָּל הָעוֹלָם אֶלָּא לָדַעַת אֶת ה' בִּלְבַד. וּלְפִיכָךְ יִהְיוּ יִשְׂרָאֵל חֲכָמִים גְּדוֹלִים וְיוֹדְעִים דְּבָרִים הַסְּתוּמִים וְיַשִּׂיגוּ דַּעַת בּוֹרְאָם כְּפִי כֹּחַ הָאָדָם. שֶׁנֶּאֱמַר (ישעיה יא, ט) "כִּי מָלְאָה הָאָרֶץ דֵּעָה אֶת ה' כַּמַּיִם לַיָּם מְכַסִּים":

At that time there will be no famines and no wars, no envy and no competition. For the Good will be very pervasive. All the delicacies will be as readily available as is dust. The world will only be engaged in knowing God. Then, there will be very wise people who will understand the deep, sealed matters. They will then achieve knowledge of the Creator to as high a degree as humanly possible, as it says, “For the Earth shall be filled of knowledge of the Lord, as the waters cover the sea” (Isaiah 11:9).

(ו) וְגָ֤ר זְאֵב֙ עִם־כֶּ֔בֶשׂ וְנָמֵ֖ר עִם־גְּדִ֣י יִרְבָּ֑ץ וְעֵ֨גֶל וּכְפִ֤יר וּמְרִיא֙ יַחְדָּ֔ו וְנַ֥עַר קָטֹ֖ן נֹהֵ֥ג בָּֽם׃
(6) The wolf shall dwell with the lamb, The leopard lie down with the kid; The calf, the beast of prey, and the fatling together, With a little boy to herd them.

Different Modern Perspectives on the Messiah

Adapted from: The Messiah and the Jews: Three Thousand Years of Tradition, Belief and Hope

Traditional Jewish views on the Messiah could not, Reformers believed, withstand the changes of Emancipation. Reform Jews prized an intellectual outlook on Judaism and valued religious tenets that could be upheld even in a rational, secular milieu. They did not, therefore, embrace traditional messianism – rooted in complicated Scriptural allusions and folklore, filled with images of apocalyptic battles, a superhuman deliverer, and even a physical resurrection of the dead. And with its emphasis on Jewish triumph over the enemies of Israel, messianism also sharply contradicted Emancipation tenets of equality and universalism. Finally, traditional Jewish messianism expressed a yearning to return to Zion, to rebuild the ancient Temple in Jerusalem, and to restore rule over Israel to the descendants of King David. Such hopes undermined the Jews’ new status as loyal citizens of Germany.

Perhaps the most powerful reason to jettison traditional messianic belief, the Reformers argued, was that it was simply not needed anymore. Human beings – guided not by a Messiah but by their own intellect – had already begun the work of redemption. Reformers believed that the principles of Emancipation would inspire every nation and bring liberation to the entire world. Spreading from Germany and taking especially strong hold in the United States, Reform Judaism abolished the concept of a divinely-sent Messiah and promised instead that humanity would accomplish its own redemption.

Rabbi Arthur Green, Seek My Face, Speak My Name

Instead of bringing about the onset of redemption, messiah will herald its completion. The actual work of redeeming the world is turned to us in history, and is done by all of us, day by day. Messiah has been waiting in the wings, as it were, since the very beginning of history, ready to come forth when the time is right. According to one legend, he sits among the lepers at the gates of Rome–today we would be likely to find him in an AIDS hospice–tending to their wounds. Only when redemption is about to be completed will messiah be allowed to arrive. Rather than messiah redeeming us, we redeem messiah.

How can we "redeem the messiah"? How can we help to bring about the messianic age?
