He appointed the moon for seasons: the sun knows his going down.
And there shall be signs in the sun, and in the moon, and in the stars; and on the earth distress of nations, with perplexity; the sea and the waves roaring;
Immediately after the tribulation of those days shall the sun be darkened, and the moon shall not give her light, and the stars shall fall from heaven, and the powers of the heavens shall be shaken:
The sun shall be turned into darkness, and the moon into blood, before the great and notable day of the Lord come:
NASA: “The frequency of Tetrads is variable over time.
“Italian astronomer Giovanni Schiaparelli first pointed out that Tetrads were relatively plentiful during one 300-year interval, while none occurred at all during the next 300 years.
“The 565-year period of the Tetrad ‘seasons’ is tied to the slowly decreasing eccentricity of Earth’s orbit.
“Consequently, the Tetrad period is gradually decreasing.
“In the distant future Tetrads will no longer be possible..
Pastor and author John Hagee, from San Antonio, Texas explains: “According to the Biblical prophecy, world history is about to change dramatically.
“To get four blood moons you need something absolutely extraordinary in astrological terms.
He believes that the four blood moons marks the dawn of a ‘hugely significant event’ for the world.
He says: “This is not something that some think tank has put together.
“NASA has confirmed that the Tetrad has only happened three times in more than 500 years – and that it’s going to happen now.”
“Every time this has happened in the last 500 years, it has coincided with tragedy for the Jewish people followed by triumph. And once again, for Israel, the timing of this Tetrad is remarkable.
“The first of the four blood moons will come on April 15 this year, during Passover. The second will be on October 8, at the time of the Feast of the Tabernacles.
“On April 4 2015, during Passover, we will have another blood moon. Then finally, on September 28, during next year’s Feast of the Tabernacles, the fourth blood and final moon will dawn.”
