Here's a start
"The mashiach will bring about the political and spiritual redemption of the
Jewish people by bringing us back to
Israel and restoring Jerusalem (Isaiah 11:11-12; Jeremiah 23:8; 30:3; Hosea 3:4-5). He will establish a government in Israel that will be the center of all world government, both for Jews and gentiles (Isaiah 2:2-4; 11:10; 42:1). He will rebuild the
Temple and re-establish its worship (Jeremiah 33:18). He will restore the religious court system of Israel and establish Jewish law as the law of the land (Jeremiah 33:15)."

and also check out
-He must build the Third Temple (Ezekiel 37:26-28)
-He must gather all the Jews back to the Land of Israel (Is. 43:5-6)
- He must usher in an era of world peace and bring an end to hatred, oppression, suffering and disease (Is. 2:4)
- He must spread the knowledge of the G-d of Israel, uniting the entire world as one (Zechariah 14:9)
why assume I never studied it? I have read and studied all sorts of fiction in my time.
No, no exceptions. Fully human. You have your beliefs about it and I have the Jewish ones.
Here, this page discusses the term "servant."
Isaiah 53: The Suffering Servant
First, the targum is not "rabbinic writings", it is an Aramaic translation/interpretation. Next, Zech 3:8 is, according to many rabbinic authorities, a reference either to Zerubavel or to the future lineage of Davidic kings (who will be anointed as such, thus Messiahs). By the way, the rabbinic authorities in the Jerusalem talmud (Ber, 2:4) say that Tzemach (which you translate as "branch") is a reference to a guy named Menachem. So while some say that it applies to a future anointed human king of the Davidic line, some see it as a reference to someone else.
