The Jewish diaspora would end and the Hebrews would poetically have their "scattered bones" mended and sinew (musles) and flesh would be restoreced and there would be another, new Jewish Nation. OT
That the 'nation without city walls' would be attacked by a coalition of nations, and God would intervene and destroy that coalition. (Isaiah)
A world leader of all the nations would solve the region's strife and offer Israel a peace treaty, which they will accept.
Another Temple will be built, and the world leader and his prophet will publically blaspheme God, and demand worship of his idol there*, and throughout the world, and forcibly register everyone in the world into his new religion and economy, then he will suddenly attack Israel himself after 3 1/2 years into the treaty.
This leader and the whole world's armies will gather together at the valley of decisions, Armageddon, and be destoyed utterly by an army of God, and the Messiah will institute his 1000 year reign. Rev.
*The Emperor Nero tried to do just that. Centuries earlier a Greek general did do it, and the Maccabees revolted and threw him out. (I II Maccabees) . Revelation.
