Some Definitions to better understand the significance of these Blood Moons.
Tishri: Is the seventh month of the religious year for Israel and the first month of the civil year for Israel. This month holds the feasts of Trumpets (Rosh Hashanah) on the 1st and Tabernacles (also known as Sukkoth) on the 15th.
Trumpets or Rosh Hashanah: This is a two day feast occurring on Tishri 1 and Tishri 2 of the Hebrew calendar. This is also called the Feast of Trumpets and falls on a New Moon.(dark)
Sukkoth or Tabernacles: The feast of Sukkoth begins on Tishri 15 on a full moon. It marks a season of rejoicing. Sukkoth means booths and refers to temporary dwelling places the Jews gather into during this holiday.
Nissan or Abib: The first month of the Jewish Religious Year – this occurs in the spring time. Passover Occurs on the 15th day of this month.
Passover: The Hebrew Feast day commemorating the Lamb Sacrifice in Exodus where the Angel of Death passed over Israel while the firstborn in Egypt were slain. It also is the same day the Lord Yeshua our lamb sacrifice for sins, was crucified.
In the Spring the Passover Feast falls on the 14th and 15th of the first month (Abib) so it is a full moon. In the Fall the Feast of Trumpets falls on the New moon or 1st of Tishri (7th month) while the Feast Tabernacles (Sukkot) falls on the 15th of the 7th month so also on a full moon.
This initial research was done by a Messianic pastor, Mark Biltz, the founder of El Shaddai ministries here in Washington. When Pastor Biltz saw a photo of a total lunar eclipse over the Dome of the Rock in 2008, it stirred his memory and curiosity.
He remembered the verse in Joel (Joel 2:31), “The sun shall be turned to darkness, and the moon to blood, before the great and awesome day of the Lord comes.” He also recalled Mark 13:24, Immediately after the tribulation of those days the sun will be darkened, and the moon will not give its light….”
The plain meaning is that these passages could refer to solar and lunar eclipses.
As it turns out, NASA has a web site (NASA Eclipse Website) that has tables of solar and lunar eclipses for thousands of years.
Pastor Biltz noticed that NASA had commented on a series of four total lunar eclipses in a row in 2014 and 2015, calling them a “tetrad.” The dates didn’t seem to mean anything, until he realized that he should be looking at the dates in the Biblical, Hebrew calendar, not our Gregorian calendar.
When he looked at them in the Hebrew calendar, he found that the first lunar eclipse in 2014 is on Passover. The second is on the first day of Succoth (Feast of Tabernacles). That seemed pretty unusual. Then he noticed that in 2015 they are on Passover and Succoth (Feast of Tabernacles) again! A lunar eclipse (blood moon) on the first and last of God’s feasts for two years in a row!
Four blood moons on four Feasts of the Lord within two years is very rare and has only occurred seven times since the time of Yeshua. There are now four blood moons scheduled to appear in 2014/2015 and then there will NOT be any for the next 100 years.
