Since the passing of the Yom Kippurim I thought it would be appropriate to look at the Mashiach. In my search of references to Him, specifically what many of the ancient sages understood and taught, I came across the site The Four Questions. Joshua has laid out some of the examples I was looking for from the Zohar, Mishna, etc.. Go here for some examples.
Here is one example:
When God desires to give healing to the world He smites one righteous man among them with disease and suffering, and through him gives healing to all, as it is written, “But he was wounded for our transgressions, he was bruised for our iniquities... and with his stripes we are healed” (Isa. 53:5). A righteous man is never afflicted save to bring healing to his generation and to make atonement for it, for the “other side” prefers that punishment should light upon the virtuous man rather than on any other, for then it cares not for the whole world on account of the joy it finds in having power over him. Yet withal another virtuous man may attain to dominion in this world and the next; he is “righteous and it is well with him,” because God does not care to make atonement with him for the world. I said to him: If all suffered alike, I could understand, but we see a righteous man in one place who is sick and suffering, and a righteous man in another who enjoys all the good things of the world. He replied: One or two of them are enough, since God does not desire to smite all of them, just as it is sufficient to let blood from one arm; only if the sickness becomes very severe is it necessary to let blood from two arms, and so here, if the world becomes very sinful all the virtuous are smitten to heal all the generation, but otherwise one is smitten and the rest are left in peace. When the people are healed the righteous are healed with them, but sometimes all their days are passed in suffering to protect the people, and when they die all are healed.
