Oh, dear. You can find as much information as you like about Rabbi Schneerson at Chabad.org.
I don't usually have occasion to speak of him, much. He was a great man, who gave advice to people from all walks of life on just about all matters, during his lifetime.
He was a leader who encouraged his "messengers" to go to different Jewish communities all over the world to ensure that there would be a "Chabad House" where
Torah would be taught to all kinds of people.
I believe that it is at his insistence that there are loads of "Mitzva Tanks" that can be seen all over the place (in NYC, they are REALLY all over the place). In any affair where there are likely to be large numbers of Jews, there are stands where "messengers" encourage Jews to lay Tefillin and recite a few prayers.
He made it a point that, wherever they were, that the "messengers" made a point that the non-Jews, wherever they were, were not left out, and that they should be taught about the Seven Noachide Laws and be made to understand that God has love for them, too.
There are many things he did, over the course of his life. I'm sure I haven't even touched the top of the tip of the iceberg when it come to relating all of the wonderful things he accomplished in his lifetime.
But with all of these wonderful things, he did not manage to convince all the Jews to move to Israel, and if you've seen the news, you know there's not world peace. So while he was a wonderful Messianic candidate, he was, alas, not the Messiah.
I'm not 100% certain. I'm sure some of it is involved in Jacob's blessing in Genesis, some of it is in Moses' blessing at the end of Deuteronomy. Some of it is involved in the discussion that various prophets had with King David.
This is one of those things that I haven't focused on verses, but understand that such is what Jewish beliefs are.
It's not as important to me to know WHERE the source of a Jewish belief is (although it is often good to know) as much as it is important to know WHAT they are.
I mean... If you want to know where I know the majority of the things I know of the Jewish expectation of the Messiah come from, I can suggest to look in Maimonides' codification of Jewish law on the section on "Laws of Kings."
I'm not sure of the verses, but I know others who do.
Back to the topic of this thread, I am very interested in the fact that the Torah, Prophets, and Books of Knowledge and Wisdom do forecast a Messiah. Christian pundits have researched these verses in the Bible and claim that Jesus fulfilled all the requirements of a Messiah. It is believed that Christ was of the same Spirit as dabar and in that sense was God in the flesh. That is why Christ told the Jews that when they saw Him that they were viewing the image of debar/logos. To the Jews this was blasphemy. Jesus used undeniable miracles to prove He was God and to prove that he had met all scripture requirements to be the Messiah, the High Priest, the Son of David, Melchisedec, king of Salem, and Savior of Jews and gentiles.
The reason I asked you what the Messiah would be like, I wanted to see if our Christ was comparable to the Messiah for which you look to come.
