Why Is a Glass Broken at the End of a Jewish Wedding?

At the end of every Jewish chuppah, the groom crushes a glass under his foot, and the crowd shouts 'Mazel Tov!'. For the uninitiated, the gesture is intriguing. For Jews, it's simply part of the landscape. But why, really? Three explanations — and the real reason is probably all three at once.

1. The Destruction of the Temple

The best-known interpretation. The broken glass recalls the destruction of the Temple in Jerusalem in 70 CE. Even in the purest joy (a wedding), the Jewish people do not forget their history. The Talmud (Berakhot 30b-31a) recounts that Rav Ashi, in the 4th century, smashed an extremely expensive crystal cup at his son's wedding to 'break' the excess of his guests' joy and bring them back to moderation.

2. The Irrevocable Commitment

A practical interpretation: once broken, a glass cannot be put back together. A Jewish marriage works the same way — committed, sealed, irrevocable. The gesture symbolizes the absolute nature of the bond created under the chuppah. This is the interpretation favored by more modern and liberal schools of thought, which emphasize the union itself.

3. Protection Against the Evil Eye

A Kabbalistic interpretation: the sound of the shattering glass drives away evil spirits that might be drawn to so much pure joy. A very old Sephardic tradition, especially present in Moroccan and Yemenite communities. Today, it's the least-cited interpretation, but it shaped the ritual for centuries.

The Technical Gesture

In practice, the glass is wrapped in a white handkerchief or a small cloth bag (to contain the shards). The groom places it on the ground, usually to the right of the chuppah, and crushes it with one decisive stomp. The glass itself is often an inexpensive kiddush cup bought specifically for this moment — some families keep the shards as a keepsake.

What Comes Next

After the glass breaks, the crowd shouts 'Mazel Tov!' and the couple exits the chuppah to music. The Sheva Brachot (7 blessings) are recited during the dinner that follows, then repeated each evening for the 7 days after the wedding, hosted by different friends and family.
