It's a jewish Kabalah thing, and the latest conspiracy nut theory.
There are some amazing co-incidences though, surround the succession of 4 'blood moons' so close together, which also happened in 1948 (the declaration of Israel) and the 6 - day war. There hadn't been 4 blood moons this close together since the middle ages, now 3 lots of 4 blood moons within just 70 years of each other. And all the blood moons fall on jewish religious days. Check it out before dismissing, this shit is about as probable as evolution, with odds so high that that you cannot rule out intelligent design.
Are the end times upon us? Will the jews inherit the earth?
