Saudi Arabia, Iran, Syria and Israel will be at the center of a total lunar eclipse, the longest of the century, which will take place on July 27-28, 2018, or 15-16 Av, 5778 on the Hebrew calendar. This is an amazing occurrence that coincides with Isaiah's prophecy, as follows:
When referring to the Geula, the full and final redemption of the Jewish People, Isaiah the Prophet says in the Name of Hashem, "B'ito, In its time, achishena, I shall hasten it" (Isaiah 60:22). Rashi explains that if the Jews so merit, the Geula will be hastened; if they don't merit, it will come anyway in its appointed time. My esteemed and beloved teacher Rabbi Shalom Arush explained to me that a "hastened" redemption will be a merciful and joyous redemption, whereas an "in its time" redemption is liable to be one of wars and strife, Heaven forbid.
The Gemara (photocopied, above) in tractate Succah 29a tells us that a Blood-moon lunar eclipse is not a good sign for Israel, especially when it is seen only here in the east and not in the west as the July 27-28 lunar eclipse will be. Yet, the Gemara in tractate Taanit 26b tells us that the 15th of Av (this year, Friday, July 27, 2018) is the best day of the year for the Jewish People. What's more, Saturday, July 28, 2018 is "Shabbat Nachamu" this year, the Sabbath of consolation, when Hashem consoles His people the Shabbat following the 9th of Av.
So what do we expect? Difficult tidings like the Gemara in tractate Succa tells us or good tidings like the Gemara in tractate Taanit tells us? The continuation of the Gemara in Succa answers that question and says: "When the Jews perform the will of Hashem, they need not worry about celestial omens. Thus says Hashem, 'Do not be frightened by the signs of the heavens' (Jeremiah 10:2)."
If we all do teshuva the best we can and strengthen ourselves in emuna, then there won't be a thing to worry about. That's why it's so important to us to spread emuna as and as wide as we possibly can. There is an amazing Heavenly hint to this in the coming lunar eclipse, as I've circled in the graphic below - the total time of the upcoming eclipse, the longest of this century, will be 6 hours, 13 minutes - 613 is the exact number of the Torah's commandments. Coincidence? No such thing...
To aid understanding, here's a clip, courtesy of our friends at the Times of India, which clearly explains the natural phenomenon of the coming lunar eclipse. Enjoy it, and may we all hear good news soon.
