Blood Moons

TIMG_3078 cropped2here has been a lot said and written about blood moons lately.[1] Some claim that the blood moons portend signs of the end times. Others claim that the blood moons are a warning to this nation. Yet others ignore them altogether as insignificant. Which interpretation is correct?

Blood moons explained

A blood moon is merely a special type of lunar eclipse. Specifically, a lunar eclipse occurs whenever the sun, earth, and moon line up such that the earth blocks the sun’s light from reaching the moon. If no light reaches the moon, we see a total lunar eclipse. However, if the geometry of the sun, earth, and moon is just right, some of the light hitting the earth’s atmosphere is bent (refracted) onto the moon’s surface. When this occurs, all colors other than the reddish colors are filtered[2] and the moon takes on a dim, dark red appearance, producing a “blood moon.”

Blood moon astronomy

Therefore blood moons may be little more than interesting astronomical phenomena. After all, Lunar eclipses are not all that rare. What is unusual, however, is that we are about to experience four blood moons within the period of about a year and all these blood moons coincide with major Jewish festivals:

  • Apr. 15, 2014 (Passover)
  • October 8, 2014 (Feast of Tabernacles)
  • April 5, 2015 (Passover)
  • September 28, 2015 (Feast of Tabernacles)

Such a series of four lunar eclipses is called a tetrad. It is a relatively uncommon event; there have been only 8 such events in the past two thousand years. If such tetrads associated with Jewish holidays are indeed Divine signs, then one should expect to see precise correlation between blood moon tetrads and significant historical events pertaining to Jerusalem, Israel, or the Jewish people.

Blood moon tetrads, Jerusalem, and Israel

The following provides a listing of blood moon tetrads and major events in Jerusalem’s history since Biblical times. It is clear from the listing that there is no correlation between blood moon tetrads and any major event in Jerusalem’s history, except for the 1967-1968 tetrad.[3]

  • 70 AD destruction of the temple
  • 132 AD Bar-Kokhba rebellion
  • 162-163 Blood moon tetrad
  • 635 Islamic conquest
  • 795-796 Blood moon tetrad
  • 842-843 Blood moon tetrad
  • 860-861 Blood moon tetrad
  • 1099 First Crusade conquers Jerusalem
  • 1187 Muslim re-conquest (Saladin)
  • 1219 City’s walls razed by al-Mu’azzam, the Sultan of Damascus
  • 1222-1243 Second Crusade reconquers Jerusalem
  • 1244-1516 Continuous wars with many changes of control (Christians, Mongols, Turks, Mamluks, Ayyubid, etc.)
  • 1493-1494 Blood moon tetrad
  • 1517 Ottoman Turks capture Jerusalem
  • 1878 First modern Jewish settlement in Israel (Petah Tikvah) – start of Zionist movement

  • 1967-1970 War of Attrition    1967-1968 Blood moon tetrad
  • 1973 Yom Kippur War
  • 1981 Operation Opera
  • 1982 – 1985 First Lebanon War
  • 1989-1992 First Intifada
  • 2000-2005 Second Intifada

  • 2014-2015 Blood moon tetrad

Blood moon tetrads and Jewish History

Jews ceased to exist as a nation in 70 AD when the Romans destroyed Jerusalem and Jews were exiled into all the nations.[4] From 70 AD until 1948 AD the Jewish people had wandered homeless among the Gentiles, constantly pursued and persecuted wherever they went. 219 instances of Jewish persecution (such as expulsion, torture, murder, and forced conversion) are listed on just one web-site covering this period.  This one list alone documents an instance of significant Jewish persecution somewhere in the world once every 10 years since Biblical times. Therefore no matter when the blood moon tetrads occur, based on simple statistics one would expect that

  1. A number (but not all) of the blood moon tetrads will coincide with some event of Jewish persecution
  2. There will be an overwhelming number of instances of Jewish persecution with no correlation to blood moon tetrads.

Blood moon tetrads meeting the above criteria have no Divine significance and are purely the product of astronomical phenomena.

Conversely, if blood moon tetrads were Divine signs, then one would expect to find

  1. Every single blood moon tetrad to be associated with some sort of rare, special, highly significant event in Jewish history.[5]
  2. Very few of such rare, special, highly significant events in Jewish history would occur without coincidence to a blood moon tetrad.

Since the Jewish people had no country, the only truly significant historical events are events leading to the founding of a country or persecution. The previous examination of Jerusalem’s history indicates no correlation between blood moon tetrads and events leading to the founding of a country. Is there any correlation between persecution and blood moon tetrads?

There are too many instances of Jewish persecution during the last 2000 years to list in this essay. Let us instead focus on the periods surrounding the eight blood moon tetrads during the same interval:

  • 162-163 Blood moon tetrad
  • 224 Italy forced conversion
  •  + 22 instances of persecution
  • 722 Byzantium Judaism outlawed
  • 795-796 Blood moon tetrad
  • 842-843 Blood moon tetrad
  • 855 Italy expulsion
  • 860-861 Blood moon tetrad
  • 876 Sens expulsion
  •  + 105 instances of persecution
  • 1492 expulsion
  • 1493-1494 Blood moon tetrad
  • 1495 Lithuania expulsion
  •    + 85 instances of persecution
  • 1938-1945 Nazi holocaust
  • 1949-1950 Blood moon tetrad
  • 1967-1968 Blood moon tetrad
  • 2014-2015 Blood moon tetrad

Not one blood moon tetrad occurs concurrently with an instance of Jewish persecution! Clearly there is absolutely no correlation whatsoever between blood moon tetrads and instances of Jewish persecution!


In summary we find the following conditions:

Expected Condition Finding
Non-Divine blood moon tetrads
1 – Some overlap between persecution and blood moon tetrad True – One overlap
2 – Much persecution without blood moon tetrad True
Divine blood moon tetrads
3 – Every blood moon tetrad would coincide with a significant Jewish event False – No overlap
4 – Very few significant Jewish events without blood moon tetrad False – Many events


Interestingly, contrary to simple statistical expectations, we find just one single instance where a blood moon tetrad coincided with an instance of Jewish persecution! Therefore we can draw the following simple conclusions:

  • Blood moon tetrads meet the statistical expectations of purely mechanistic astronomical phenomena.
  • There is minimal correlation between blood moon tetrads and significant events in Jewish history.
  • Blood moon tetrads clearly fail the test for Divine significance.
  • The argument for Divine significance of blood moon tetrads is based on sloppy and incomplete historical analysis and faulty understanding.

In fact, the almost negative correlation between blood moon tetrads and historical events could be Divine signs to teach us the foolishness of dabbling in astrology by using astronomical phenomena to try and predict the future!  Instead let us be like the Bereans who searched God’s Word diligently to find the truth.  (Act 17:11)

All is not as it looks!

[4] This event fulfilled God’s Biblical prophecies and promises to the Jews that they would be expelled from the land if they did not obey their LORD God. (Zec 13:7, Luk 19:42-44)

[5] Unfortunately no single instance of Jewish persecution meets the standard of being rare, special, or highly significant: It is merely a “normal” state of Jewish existence! Please do not misunderstand this statement. It does not condone persecution of Jews, nor does it justify it. It is merely a blunt statement of historical fact.

    Well when you put the facts into this discussion, there is no need to speculate…Ha ha. Thanks for the research!
