In the Bible, Revelation 2:9 and 3:9 warns of False Jews in the end times. The false Jews have been existence for now more than 100 years, and they refer to themselves as Zionists.
Zionists are those who believe themselves to be God's chosen people, and they have a birth right to the land of Israel. Today, they are the political influence responsible for the genocide and apartheid of Palestine, war and conflict throughout the region, the fear mongering relating to Iran's supposed nuclear weapons program, and even the calling for of President Obama's assassination in an effort to help accelerate the war against Iran.
Please see the following YouTube videos about how Israel came to be, as well as why Zionists are false Jews, as told by Orthodox Jews.
