The thirty-third day of the Omer is an occasion for happiness during an otherwise mournful period.

Few of the many couples who marry on Lag Ba'Omer give much thought to why this is one of the very few days between Pesah and Shavuot when Jewish law permits weddings. If they were to investigate, they would find a conflicting array of explanations, all appealing, none definitive.

Why We Celebrate

The explanations begin with the Omer period itself, those forty-nine days that are counted off one by one between the two festivals. This is a time of semi-mourning, when weddings and other celebrations are forbidden, and as a sign of grief, observant Jews do not cut their hair.

Anthropologists say that many peoples have similar periods of restraint in the early spring to symbolize their concerns about the growth of their crops. But the most often cited explanation for the Jewish practice comes from the Talmud, which tells us that during this season a plague killed thousands of Rabbi Akiva's students because they did not treat one another respectfully. The mourning behavior is presumably in memory of those students and their severe punishment.

According to a medieval tradition, the plague ceased on Lag Ba'Omer, the thirty-third day of the Omer.  (The Hebrew letters lamed and gimel which make up the acronym "Lag" have the com­bined numerical value of 33.) As a result, Lag Ba'Omer became a happy day, interrupting the sad­ness of the Omer period for twenty-four hours.

The talmudic explanation makes most sense when put into historical context. The outstand­ing sage Rabbi Akiva became an ardent supporter of Simeon bar Koseva, known as Bar Kokhba, who in 132 C.E. led a ferocious but unsuccessful revolt against Roman rule in Judea. Akiva not only pinned his hopes on a political victory over Rome but believed Bar Kokhba to be the long-awaited Messiah. Many of his students joined him in backing the revolt and were killed along with thousands of Judeans when it failed. The talmudic rabbis, still suffering under Roman rule and cautious about referring openly to past rebellions, may have been hinting at those deaths when they spoke of a plague among Akiva's students. Possibly, also, Lag Ba'Omer marked a respite from battle, or a momentary victory.

A completely different reason for the holiday concerns one of Rabbi Akiva's few disciples who survived the Bar Kokhba revolt, Rabbi Simeon bar Yohai. He is said to have died on Lag Ba'Omer.

Rabbi Simeon continued to defy the Roman rulers even after Bar Kokhba's defeat, and was forced to flee for his life and spend years in solitary hiding. Legend places him and his son Eleazar in a cave for twelve years, where a miraculous well and carob tree sustained them while they spent their days studying and praying. When they finally emerged, Simeon denigrated all practical occupations, insisting that people engage only in the study of Torah. For this God confined the two to their cave for another year, accusing Simeon of destroying the world with his rigid asceticism.
