In his latest book, Four Blood Moons: Something Is About to Change, Hagee lays out what he calls celestial signals. He describes how a series of blood moons in 2014 and 2015 will have great significance for Israel.
Although single blood moons happen fairly regularly, four appearing so closely together is extremely rare. There have only been a series of blood moons a handful of times over the past 500 years.
So what exactly is a blood moon and what is the biblical significance?
"A blood moon is when the Earth comes between the sun and the moon," Hagee explained. "And the sun is shining through the atmosphere of the Earth and casts up on the moon a red shadow. And so the moon appears to be red."
Such moons appear several times in scripture.
In the book of Joel, God says there will be "wonders in the heavens and in the earth, blood, and fire…the sun will be turned to darkness and the moon to blood before the coming of the great and dreadful day of the Lord."
In Acts, the Apostle Peter repeats that verse from Joel. And the book of Revelation says that during the Great Tribulation, "the moon will become like blood."
Blood moons are set to appear in April 2014, on Passover, and then again in September 2014 during the Feast of Tabernacles, or Sukkot.
The timing is the same for 2015 -- a total of four blood moons, all appearing on Jewish feast days.
"The sun and the moon and the Earth are controlled by God almighty," Hagee said. "He is the one that is getting them in a direct alignment on a certain day at a certain time -- but each time, it's a Passover or Sukkot.
Historic Significance
In the past, the rare appearance of four blood moons on these feast days has coincided with major events for Israel and the Jewish people.
