Isaiah 2:1 - 4
1 The word that Isaiah, son of Amoz, prophesied concerning Judah and Jerusalem. 2 And it shall be at the end of the days, that the mountain of the L-rd's house shall be firmly established at the top of the mountains, and it shall be raised above the hills, and all the nations shall stream to it. 3 And many peoples shall go, and they shall say, "Come, let us go up to the Lord's mount, to the house of the G-d of Jacob, and let Him teach us of His ways, and we will go in His paths," for out of Zion shall the Torah come forth, and the word of the L-rd from Jerusalem. 4 And he shall judge between the nations and reprove many peoples, and they shall beat their swords into plowshares and their spears into pruning hooks; nation shall not lift the sword against nation, neither shall they learn war anymore.
Isaiah 25:8 - 9
8 He has concealed death forever, and the Lord G-d shall wipe the tears off every face, and the shame of His people He shall remove from upon the entire earth, for the L-rd has spoken. 9 And they shall say on that day, "Behold, this is our G-d: we hoped for Him that He would save us; this is the L-rd for Whom we hoped; let us rejoice and be happy with His salvation.
It also says none but G-d will be exalted, Jew and gentile will know G-d and no one will know suffering anymore. He will also be a judge. A little more then an "enlightened man". The Tanakh says the spirit of G-d will be upon him.
