Why Do We Mourn During the Omer? The Meaning Behind the Customs

Moti asks: “Why do we mourn during the days of the Omer by avoiding haircuts and music for an entire month, yet we do not mourn the Holocaust in the same way? After all, more than 24,000 Jews were killed in the Holocaust. And why do we continue mourning during the Omer for something that happened thousands of years ago?”

Hello Moti, and thank you for your thoughtful questions.

Regarding your first question: on Tisha B'Av, the Jewish people mourn the destruction of the Temple in Jerusalem, and together with it all the persecutions, suffering, pogroms, and tragedies that followed the exile.

During the destruction of the Temple itself, nearly one million Jews were killed, and many hundreds of thousands more were murdered throughout the long years of exile and persecution. The fast days connected to the exile were established to commemorate these tragedies.

Therefore, the mourning observed on Tisha B’Av also includes the suffering of later generations, including the Holocaust, in which six million Jews were murdered.

The Purpose of Days of Mourning

Maimonides explains that days of mourning were established to remind every generation to repent for the sins that led to destruction.

He writes: “There are days when all of Israel fasts because of the tragedies that occurred on them, in order to awaken the hearts and open the paths of repentance. They serve as a reminder of our own wrong actions and those of our ancestors, which caused these calamities to befall them and us. By remembering these events, we will return to better conduct.”
(Mishneh Torah, Laws of Fasts, Chapter 5)

The Tragedy of Rabbi Akiva’s Students

Between the end of Passover and the thirty-fourth day of the Omer, 24,000 students of Rabbi Akiva died.

Because of this tragedy, mourning customs are observed throughout this period.

These students were not simply a large group of Jews, but were the Torah scholars of their generation, the teachers who preserved and transmitted the Torah to the entire Jewish people.

The Guardians of Jewish Identity

Torah scholars are the ones who safeguard the Torah and the Jewish identity. They are the spiritual leadership and the unifying force of the Jewish people throughout history.

Just consider what happened after thousands of years of exile: Jews returned to the Land of Israel from Iraq, Tunisia, Egypt, Yemen, Poland, Germany, Russia, the United States, and many other countries.

They arrived with different languages, appearances, clothing, and customs.

Yet one thing united them all: the Torah. They returned with the same Tanach, the same tzitzit, the same tefillin, the same Shabbat, and the same Passover.

Without the Torah, the Jewish people could easily have disappeared through assimilation among the nations.

A Loss That Endangered the Future of Torah

When those 24,000 students died in one generation, the Jewish people did not only lose many precious individuals, but they lost the Torah leaders of the generation.

These scholars represented the majority of the Torah sages of their time. Their passing endangered the transmission of Torah knowledge and, with it, the very survival of Jewish identity in exile.

Therefore, the mourning during the Omer is also for the loss of Torah greatness in the generation of Rabbi Akiva — a loss that continues to affect us today.

According to this perspective, deeper levels of Torah wisdom became hidden from us because of that tragedy. They will only be fully revealed again with the coming of Mashiach and the rebuilding of the Temple.

Carrying the Torch of the Jewish People

Anyone who observes the mourning customs of the Omer connects himself to two thousand years of shared Jewish experience and to the deep love of Torah that unites Jewish communities throughout the world.

In doing so, he testifies to his faith in God and His Torah, about which it is written: “If not for My covenant day and night, I would not have established the laws of heaven and earth.” (Yirmiyahu 33:25)

A Powerful Moral Lesson

The mourning during the Omer also carries a profound ethical lesson.

Where else in the world can you find a nation that continues to mourn for nearly two thousand years over the loss of Torah scholars? The yearly remembrance reinforces in our hearts the importance of the Torah and of the sages who protect the spiritual life of the Jewish people.

Just as modern countries establish memorial days for fallen soldiers, the Jewish people established days of remembrance for the “army” of Torah scholars who preserved our identity.

The Lesson of Respect for Others

The Talmud explains that the students of Rabbi Akiva died because they did not treat one another with sufficient respect (Yevamot 62b).

This does not mean they insulted one another or spoke negatively. Rather, according to their lofty spiritual level, they failed to show the full measure of honor required of them.

This tragedy serves as a powerful reminder of the importance of respect between people, especially among Torah scholars.

The Torah commands: “Love your fellow as yourself; I am the Lord.” (Vayikra 19:18)

Why the Mourning Continues Today

We continue mourning because the spiritual consequences of those events have not yet disappeared. Our sages taught: “Any generation in which the Temple is not rebuilt is considered as if it was destroyed in that generation.” (Jerusalem Talmud, Yoma 1:1)

This means that we have not yet reached the spiritual level necessary for the rebuilding of the Temple.

Until the coming of Mashiach and the final redemption, mourning expresses our sorrow over the spiritual loss and our desire to return to God.

Mourning as a Path Toward Redemption

Through these customs, we awaken divine mercy and help bring the redemption closer.

The sages taught: “Whoever mourns for Jerusalem will merit to see its joy.” (Taanit 30b)

Even if not in this lifetime, then in the future resurrection.

Likewise, those who mourn the loss of Torah scholars will one day witness the glory of the Torah and the redemption, when: “They will neither harm nor destroy in all My holy mountain, for the earth will be filled with knowledge of God as the waters cover the sea.” (Yeshayahu 11:9)

We must remember that this mourning is temporary. The prophets foretold that when the complete redemption arrives, these days of fasting and mourning will be transformed into days of joy and celebration, as it is written in Book of Zechariah 8:19.

What Mourning During the Omer Teaches Us

Through observing the mourning customs of the Omer:

1. We are reminded to repent and improve our actions, as taught by Maimonides.

2. We connect ourselves to the ancient and enduring story of the Jewish people.

3. We share in the responsibility to repair the spiritual damage that still affects us.

4. We affirm the importance of Torah and Torah scholars.

5. We remember the obligation to honor and respect one another.

6. We help bring the redemption closer by awakening divine compassion.

May the day soon come when mourning will turn to joy and the Jewish people will witness the full glory of the Torah and redemption.
