1. What’s in a Name?

The 11th month of the Jewish year (counting from Tishrei) is also referred to as “Menachem Av.” “Menachem” means “consoler,” and “Av” means “father.” Due to the tragic events that occurred during this month, its name reminds us that G‑d is there to comfort us in times of tragedy.


2. The Month of the Lion

The astrological sign of Av is the lion, which represents tragedy and potential for redemption. Our sages teach, “The lion [Babylonian King Nebuchadnezzar] came, under the constellation of lion [Leo], and destroyed the Lion of G‑d [Jerusalem] . . . so that the Lion [Moshiach] shall come, under the constellation of lion, and build the Lion of G‑d [Jerusalem]."

The Talmud relates that Moshiach was born on the very day when the Temples were destroyed: the 9th of Av. Moshiach was born from the tribe of Judah, whose symbol is the lion. This teaches us that the tragedies and suffering associated with the 9th of Av will turn into joy with the coming of Moshiach.


3. A Time of Mourning

The first nine days of Av are a period of mourning. We refrain from eating meat and drinking wine, except on Shabbat and on celebrations, such as a bar mitzvah, a brit (circumcision) or the completion of a tractate of the Talmud.

We also refrain from washing clothing (except for those of a baby) and wearing freshly washed clothing, swimming and bathing for pleasure, and remodeling a home. We avoid unnecessary travel, and postpone the sanctification of the moon and celebrating a couple’s engagement until after Tisha B’Av.

On a spiritual level, we also take time to increase mitzvah observance and our performance of kind deeds to improve the world.


4. The Yahrtzeit of Aaron

Aaron, the first High Priest, brother of Moses and Miriam, passed away at age 123 on the 1st of Av of the Jewish year 2487 (1274 BCE). It’s the only yahrzeit (date of passing) explicitly mentioned in the Torah (Numbers 33:38).


5. A Day of Remembering a G‑dly Man

The 5th of Av is the yahrtzeit of Rabbi Isaac Luria Ashkenazi, known as Ari HaKadosh ("The Holy Lion"), who passed away in the Jewish year 5332 (1572 CE). Born in Jerusalem in 1534, he spent many years in secluded study near Cairo, Egypt, and moved to Safed in 1570, where he died two years later at age 38. The Ari, who is regarded as one of the most prominent figures in Jewish mysticism, made the study of Kabbalah mainstream.


6. The Worst Day in the World

On the 9th of Av, we commemorate several tragedies, among them: The Jews who left Egypt with Moses were condemned to wander and die in the desert for 40 years; the destruction of both Holy Temples by the Babylonians in 423 BCE and by the Romans in 69 CE; and the Jews of Betar who were killed.

Later in history, in 1290, the Jews of England were expelled by King Edward; and the Jews of Spain were expelled by King Ferdinand and Queen Isabella in 1492. In 1942, the deportation of Jews from the Warsaw ghetto to the Treblinka extermination camp began.

The day is commemorated as a day of fasting and mourning.

7. The Shabbat Prior to the Ninth of Av Is Called ‘Shabbat Chazon

Shabbat Chazon” is translated to “Shabbat of the Vision.” On this Shabbat, the reading from the Prophets begins with the words “Chazon Yeshayahu,” the vision of Isaiah, regarding the destruction of the Holy Temple. In Chassidic teachings, we learn that every Jewish soul is shown a vision of the third Holy Temple, inspiring us to do mitzvot to turn this vision into reality.


8. We Read the Book of Lamentations on the 9th of Av

In the book of Lamentations, the prophet Jeremiah recorded the imminent destruction of the First Temple and the exile of the Jewish people.

G‑d instructed Jeremiah to write down the words. He spoke about Israel and Judah in order to warn the house of Judah about tragedies that would occur if they did not repent. Jeremiah, imprisoned at the time, dictated three chapters to his student, Baruch ben Neriah, who wrote down the impending tragedies in past tense, as though they had already occurred. Per Jeremiah’s instruction, Baruch read the scroll to the Jewish people, who had gathered at the Temple. Rashi relates that the scroll was read before King Jehoiakim, who, after hearing just a few verses, threw the scroll into the fireplace.

As Jeremiah prophesied, on the 9th of Av, the Temple were destroyed and the Jews were led into captivity. Ever since this tragedy, we read the book of Lamentations on the eve of the 9th of Av.


9. The 15th of Av Is Known as One of the Happiest Days in Jewish History

This day, Tu B’Av, signifies rebirth after destruction and is a day for new beginnings. On this day, the daughters of Jerusalem would borrow linen garments in order not to embarrass others who did not have beautiful clothing and dance in the vineyards to find prospective grooms.

The Talmud considers this day the greatest festival of the year, followed by Yom Kippur, as its essence represents the future redemption.


10. Remembering a Father

The 20th of Av marks the yahrtzeit of the Lubavitcher Rebbe’s father, Rabbi Levi Yitzchak Schneerson (1878-1944), in Alma Ata, Kazakhstan. Rabbi Levi Yitzchak was Chief Rabbi of Yekaterinoslav (currently Dnipro, Ukraine), and was arrested and exiled to Kazakhstan by the Stalinist regime as a result of his work to preserve Jewish life in the Soviet Union.
