Why the "Jewish Messiah Prophecy" haunts Benjamin Netanyahu

Benjamin Netanyahu was told by a powerful Jewish religious figure The REBBE that he would be Israel’s last leader and hand the sceptre to the Messiah. How does this so-called prophecy affect Netanyahu’s political calculations? And who is the mysterious religious figure, honoured by successive US presidents , simply known as The Rebbe?

Benjamin Netanyahu quotes the bible a couple times in this video.
My favorite Bible quotes from the Book of Revelations is 2:9 & 3:9
Revelation 2:9
I know thy works, and tribulation, and poverty, (but thou art rich) and I know the blasphemy of them which say they are Jews, and are not, but are the synagogue of Satan.

Revelation 3:9
Behold, I will make them of the synagogue of Satan, which say they are Jews, and are not, but do lie; behold, I will make them to come and worship before thy feet, and to know that I have loved thee.
