They will come and go as they always have. In the aftermath false prophets will come up with new prophecies to hopefully distract people and make them forget.
I think you’re confusing this as a prophecy in the Bible. Let me put it another way, which may make it clearer - you could say that the Bible never existed and that there are no prophecies at all — and we would STILL be looking at this.
This has nothing to do with the Bible or prophecies - in and of itself. This is seeing a PATTERN (keeping in mind we would be looking at the same pattern, even if the Bible didn’t exist).
Here’s the pattern from the past ...
The Blood Red Moons Of 2014 And 2015: An Omen Of War For Israel?
Four TOTAL lunar eclipses occurred on the Jewish Passover and Feast of Tabernacles in 162 163 AD, coinciding with the worst persecution of Jews and Christians in the history of the Roman Empire. Within 3 years the Antonine Plague killed eight million people, a third of the population.
Four TOTAL lunar eclipses occurred on the Jewish Passover and Yom Kippur Holidays in 795 796 AD while King Charlemagne of the Holy Roman Empire established a DMZ buffer zone between France and Spain, ending centuries of Arab invasions into Western Europe.
Four TOTAL lunar eclipses occurred on the Jewish Passover and Yom Kippur Holidays in 842 843 AD. Shortly after the eclipses the Vatican church in Rome was attacked and looted by an Islamic invasion from Africa.
Four TOTAL lunar eclipses occurred on the Jewish Passover and Yom Kippur Holidays in 860 861 AD. Shortly after the eclipses the Byzantine Empire defeated Arab armies at the Battle of Lalakaon in Turkey and permanently stopped the Islamic invasion of Eastern Europe.
Four TOTAL lunar eclipses occurred on the Jewish Passover and the Feast of Trumpets Holidays in 1493 1494. Only months after King Ferdinand and Queen Isabella of Spain ordered all Jewish people to leave the country (after about 200 AD, Spain became and remained a second Jewish homeland for well over a millennia. So deeply woven into the fabric of Spain are the Jews that neither history can be fully studied without considering the influence of the other).
And to these listed above, are two more - the establishing of the State of Israel, and Israel gaining full sovereignty over Jerusalem.
Oh ... and one more thing about this you may be missing ... it’s not talking about simply blood moons, but about the TETRADS (loosely meaning four in a row).
