Adon HaMelech Moshiach

ואם יעמוד מלך מבית דוד הוגה בתורה ועוסק במצות כדוד אביו, כפי תורה בכתב ושבעל פה, ויכוף כל ישראל לילך בה ולחזק בדקה, וילחם מלחמות ה׳, הרי זה בחזקת שהוא משיח, אם עשה והצליח ובנה מקדש במקומו וקבץ נדחי ישראל הרי זה משיח בודאי, ויתקן את העולם כולו לעבוד את ה׳ ביחד שנאמר כי אז אהפוך אל עמים שפה ברורה לקרוא כולם בשם ה׳ ולעבדו שכם אחד.

Rambam

If a king will arise from the House of David who delves deeply into the study of the Torah and, like David his ancestor, observes its mitzvos as prescribed by the Written Law and the Oral Law; if he will compel all of Israel to walk in [the way of the Torah] and repair the breaches [in its observance]; and if he will fight the wars of G-d – he is presumed to be Moshiach. If he succeeds in the above, builds the Beis Hamikdash on its site, and gathers in the dispersed remnant of Israel, he is definitely the Moshiach. He will then perfect the entire world, [motivating all the nations] to serve G-d together, as it is written (Zephaniah 3:9), "I will make the peoples pure of speech so that they will all call upon the Name of G-d and serve Him with one purpose".
............................................

By tradition some claim If Messiah is killed before fulfilling all these:

1.) Compel all of Israel to walk in the way of Torah 
2.) Repair the breaches in observance 
3.) Fight the wars of G-d 
4.) Build the Beis Hamikdash in its place 
5.) Gather in the dispersed exiles of Israel

...then he isnt Messiah which I see as a ideology only supported by those who saw the true Messiah as a threat (to their own social status and power) and didnt allow for all scripture to apply or even Jewish commenaries of many Jewish sages. This type of ideology was allowed to take hold that G-d's will be done.
אנו חײבים להאמין שבא יבא איש יהודי והוא יחל להושיע את ישראל והוא יגמור ישועת יעקב באותו הדור, ומי שיגמור הדבר הוא הוא ומי שלא יגמור באותו הדור ומת או נשבר או נשבה אינו הוא ולא אלקים שלחו.
We are obligated to believe that if a Jewish man comes and begins to save the Jews and he completes the salvation of Israel in that generation, if he finishes the job then he is [Moshiach]. However, whoever does not finish the job but dies or is broken or is captured then he is not [Moshiach] and G-d did not send him. 

ואם לא הצליח עד כה או נהרג, בידוע שאינו זה שהבטיחה עליו תורה... ולא העמידו הקדוש ברוך הוא אלא לנסות בו רבים.

But if he did not succeed in all this or was killed, he is definitely not the Moshiach promised in the Torah... and G-d only appointed him in order to test the masses.
אבל אמונתנו ואמונת כל יהודי שאם יבא אדם ויקבץ נדחי ישראל ויבנה מקדש וכל העמים יאספו אליו ויקראו כולם בשם קל אז נאמר כי הוא משיחנו. וכל מאמר שיאמר היפך זה יש לו פירוש.
Our belief and the belief of every Jew is that if a man comes, gathers the dispersed of Israel, builds the Temple, and all the nations gather to him and call out unanimously in the name of G-d, then we will say that he is Moshiach. Any statement that contradicts this has an explanation. (Shevet Yehuda p. 105)
 ולכאורה עכצ״ל שאין דוד המלך בעצמו מלך המשיח שיהי׳ ״נשיא להם לעולם״, שהרי תחילת פעולת מלך המשיח תהיה קודם הגאולה, כמבואר ברמב״ם (הל׳ מלכים פי״א ה״ד), ובודאי קודם תחײת המתים (גם דצדיקים הקמים מיד, כחז״ל (יומא ה,ב) משה ואהרן עמנו).
Evidently, we must say that David HaMelech cannot himself be the Melech HaMoshiach who will be "a leader for them forever" because the initial work of the Melech HaMoshiach will be before the redemption, as explained in the Rambam (Hilchos Melachim 11:4) and certainly before the resurrection (including the righteous who arise immediately, as Chazal say (Yoma 5b) "Moshe and Aharon with us"). (Likutei Sichos vol. 35 p. 206 n. 6) 

......................................

ואח״כ יעמוד מלך עז פנים שלשה חדשים, ואח״כ תמלוך מלכות הרשעה על ישראל תשעה חדשים... ויצמח להם משיח בן יוסף ויעלה אותם לירושלם ויבנה בית המקדש ויקריב קרבנות ותרד אש מן השמים ותאכל קרבנותיהם... אם לא זכו משיח בן אפרים בא ואם זכו משיח בן דוד ויעמוד מלך רשע ושמו ארמילוס... וישראל גולין למדברי אגמים לרעות במלוחים ובשרשי רתמים מ״ה ימים, ואז נבחנים ונצרפים שנאמר והבאתי את השלישית באש וגו׳. וימות שם משיח בן אפרים וישראל סופדים אותו, ואח״כ יגלה להם להם הקב״ה משיח בן דוד, וישראל ירצו לסקלו ואומרים לו שקר דברת שכבר נהרג משיח ואין משיח אחר עתיד לעמוד ויבזוהו... והוא חוזר לו ונכסה מהם... ובצר להם לישראל הם חוזרים וצועקים מרעב ומצמא ומיד נגלה להם בכבודו.

Afterwards, the evil government will rule over Israel for nine months... Moshiach ben Yosef will arise and then bring them to Jerusalem where they will build the Temple, offer sacrifices, and fire will come down from heaven and deavour the sacrifices... If they do not merit it, Moshiach ben Efraim [i.e. Yosef] will come but, if they merit it, Moshiach ben David will come. An evil king named Armelius will arise... He will go to Jerusalem and battle Moshiach ben Yosef in the east gate... The Jews will flee to the desert to feed on salt land and roots of weed for 45 days. They are then tested and purified as it says (Zechariah 13:9), "I will bring a third in fire..." Moshiach ben Efraim will die there and Israel will mourn him. After this, G-d will reveal to them Moshiach ben David and the Jews will want to stone him. They will say that he is lying because Moshiach was already killed and another Moshiach will not arise. They will insult him... and he will

ומלך המשיח יצמח שם... ויפיח באותו ארמילוס הרשע וימיתהו... והקב״ה שורק ומקבץ כל ישראל ומעלם ירושלם...

return and be concealed from them... After this, the Jews will return and cry out from hunger and thirst and G-d will immediately reveal Himself to them in His glory... The king Moshiach will arise there... and will blow at Armelius thereby killing him... G-d will whistle, gather all the Jews, and bring them to Jerusalem... (Otzar HaMidrashim p. 551)

(Moshiach is unknown to the Jews (Judasim) prior to him arising as Messiah Ben Yoseph (role of the 2nd Advent of Yeshua. )

ולענין היאך יעמוד משיח והיכן יעמוד הרי הוא יעמוד בארץ ישראל דוקא ובה תחל התגלותו... ולענין היאך יעמוד, הוא לא יודע כלל לפני עמדו והוא אינו משיח עד שיאמר פלוני בן פלוני מבית אב פלוני, אלא יעמוד אדם שאינו ידוע לפני התגלותו.

Regarding how and where Moshiach will arise, he will arise specifically in the land of Israel and there will begin his revelation... Regarding how he will arise, he will not be known at all before his arising while he is not the Moshiach, so that it would be said about him such-andsuch from such-and-such family. Rather, a man will arise who will be unknown before he is revealed. (Iggeres Teiman, ed. Kafah p. 52)

אי אפשי להאמין במשיחותו שהנביא אומר ״ומשלו מים עד אפסי ארץ״ והוא לא היה לו ממשלה... וכן הנביא אומר שבזמן המשיח ולא ילמדו עוד איש את רעהו ואיש את אחיו לאמר דעו את ה׳ כי כולם ידעו אותי וכו׳ ואומר כי מלאה הארץ דעה את ה׳ כמים לים מכסים ואומר וכתתו חרבותם וכו׳ ולא ישא גוי אל גוי חרב ולא ילמדו עוד מלחמה ומימי ישו ועד הנה כל העולם מלא חמס ושוד.

I cannot believe in his messiahship because the prophet says (Tehillim 72:8) "He will have dominion from sea to sea, and from the River to the ends of the earth" and he [Jesus] did not have dominion... The prophet also says (Yirmiyahu 31:33) "No longer shall they teach one another, or say to each other, 'Know the Lord,' for they shall all know Me..." And it says (Yishayahu 11:9) "The earth will be full of the knowledge of the Lord as the waters cover the sea." It says (Yishayahu 2:4) "they shall beat their swords [into plowshares, and their spears into pruning hooks;] nation shall not lift up sword against nation, neither shall they learn war any more." But from the time of Jesus until now the world is full of murder and theft... (Kisvei HaRamban vol. 1 p. 311)

- Bamidar Rabbah 11:2, "Like Moses, Messiah will be revealed, then hidden, then revealed again."

- "Moshiach [King Messiah] will thereupon rise up to Heaven just as Moshe [Moses] ascended to the firmament, and will subsequently [return and] be revealed completely for all to see. The entire Jewish people will then perceive him and flock towards him." From Arba Mei'os Shekel Kesef(page 68) ...written by Rabbi Chaim Vital, pupil of the Arizal...

A less well known is that some post-Biblical rabbis actually held much the same belief in Jesus. For example, a Midrash states, "The son of Rabbi Joshua ben Levi had a choking fit. He [Rabbi Joshua] went and brought one of the followers of [Jesus] to relieve his son's choking" (Midrash Rabbah, Ecclesiastes 10:4:1).And according to a Medieval rabbi, Menachim of Speyer, "A Christian may be permitted to heal a Jew even if he invokes the aid of Jesus and the Saints." Even Maimonides wrote, "Ultimately, all the deeds of Jesus of Nazareth . . . will only serve to prepare the way for the Messiah's coming and the improvement of the entire world" (Mishnah Torah: Hilchot Melachim U'Milchamoteihem 11:4).According to Luke, the common Jewish people flocked to Jesus. For example, the first 5,000 Christians were Jews (Acts 4:4)Nicodemus, a "leading Jew" hailed him as "a teacher who comes from God" (John 3:1-2). And Rabbi Gamaliel, a member of the Sanhedrin and later Paul's teacher, declared, "If [Christianity] comes from God you [members of the Sanhedrin] will not only be unable to destroy [it], but you might find yourselves fighting against God" (Acts 5:34-39) Elsewhere, the Sanhedrin itself concluded, "It is obvious to everybody in Jerusalem that a miracle . . . has been worked through [Christ's disciples] in public and we cannot deny it" (Acts 4:16).

Maimonides writes in the Mishnah Torah, "Jesus of Nazareth . . . aspired to be the Messiah and was executed by the court" (Hilchot Melachim U'Milchamoteihem 11:4). Also, the Talmud states:

"On the eve of the Passover, Jesus of Nazareth was [crucified]. For 40 days before the execution took place, a herald went forth and cried, 'Jesus of Nazareth is going to be stoned because he is guilty of practicing sorcery and enticing the people to apostasy. Anyone who can say anything in his favor, let him come forward and plead on his behalf.' But since nothing was brought forward in his favor he was [crucified] on the eve of the Passover . . . Rabbi Ulla asked, 'Do you suppose that he was one for whom a defense could have been made?' [And then he answered his own question by stating,] No, because with Jesus of Nazareth it was different, for he was descended from the royalty." (Tr. Sanhedrin 43a)

Another point of interest in this Talmudic text is that it openly acknowledges Jesus to have been "descended from the royalty" (i.e., the Throne of David), which implies that He was a legitimate heir, in their eyes, to the office of Messiah -- and, furthermore, it was because of that very royal lineage that "a defense could not be made" on his behalf, as stated by Rabbi Ulla in the Gemara in question.

Shortly after Jesus announced that he was the "Son of God," He went to the home of Mary and Martha in Bethany. There He proclaimed the next stage of His vocation: "I am the resurrection . . . If anyone believes in me, even though he dies he will live" (Jn 11:25). Then, as if to prove this bold assertion, He raises Lazarus from the dead (Jn 11:43-44).

"Then the chief priests and Pharisees called a meeting. 'Here is this man working all these signs,' they said, 'and what action are we taking? If we let him go on this way everybody will believe in him and the Romans will come and destroy the Holy Place and our nation.' One of them, Caiaphas, the high priest that year, said, 'You don't seem to have grasped the situation at all: you fail to see that it is better for one man to die for all the people than for the whole nation to be destroyed.' He did not speak in his own person, it was as high priest he made this prophecy that Jesus was to die for the nation -- and not for the nation only, but to gather together in unity the scattered children of God. From that day they were determined to kill him." (Jn 11:47-53)."

"When God desires to give healing to the world He smites one righteous man among them . . . and through him gives healing to all . . . A righteous man is never afflicted save to bring healing to his generation and to make atonement for it."(Zohar 5:218a)

"[The] Messiah [ben Joseph] will . . . be slain and lay in the streets for three days. Then . . . the prophet Elijah will go and revive [him] . . . And in the hour when the Tribes of Israel will come forth, Clouds of Glory will go before them. And the Holy One, blessed be He, will open for them the sources of the Tree of Life, and will give them to drink on that day." (Otot HaMashiach)

"And then the Community of Israel communes with the Holy One, blessed be He, and that hour is a time of grace for all, and the King [Messiah] holds out to [Israel], and all who are with her, his scepter of the thread of grace so that they all may be wholly united to the Holy King." (Zohar 5:45a)

a Mishnah by Maimonides states,

"If a king will arise from the House of David [who] . . . gathers the dispersed of Israel [as Caiaphas believes Jesus could do], he is definitely the Messiah." (Mishnah Torah: Hilchot Melachim U'Milchamoteihem 4:11)

______________

"In order to give all of mankind the option of living according to the Torah's precepts, the Lord offered it to each nation of the world. . .[Gentile] nation after nation refused to accept [it] . . . Finally, the Lord approached Israel: 'Will you accept my Torah?' . . . Not only were they willing to receive the Torah but they did so even before knowing what it contained." (Tr. Avodah Zara 2b)

Moreover, the same Gemara continues: "The Gentiles will eventually regret their decision and plead, 'Offer us the Torah again and we shall obey it.' But the Holy One, blessed be He, will say to them, 'You foolish ones among the peoples, he who took the trouble to prepare on the even of the Sabbath can eat on the Sabbath, but he who has not troubled on the eve of the Sabbath, what shall he eat on the Sabbath?'"

In other words, Gentiles are forbidden, by rabbinic law, from practicing Judaism because they rejected the Torah when it was offered to them. This belief was and is so strong that the Talmud and Midrash state: "If a Gentile is learning Torah or keeping the Sabbath in the manner of Jews . . . he is liable for capital punishment by the rabbinic court." (Quoted in Chaim Clorfene and Yakov Rogalsky, The Path of the Righteous Gentile, p. 42)

the proper observance of Torah for righteous Gentiles is "Noahism," in which they join the Community of Israel by following the "Seven Laws of Noah". It was within this belief system that the Jewish leaders brought Paul before the Corinth Tribunal, not because he taught Christianity, but because he taught it to the Gentiles in a manner that permitted them to worship as Jews. For that reason, I submit, and not because he taught Christ, they accused him of "persuading people to worship God in a way that breaks the law." This may have been another way of saying, "Paul is encouraging Gentiles to break the law by worshiping God as if they were Jews rather than Noahites."/ (Acts 15:1)
