In synagogue on Saturday, as we read Parsha Noach, I was reminded by the brilliant young woman who was becoming a bat mitzvah, about the number 40 appearing again and again throughout Jewish tradition.
For 40 days and nights, rain fell upon the earth, washing away the world Noah had known. G-d instructed Noah to build an ark, a place of protection and preservation. But when the waters receded, Noah could not remain inside. He had to step into an unfamiliar world and begin again. G-d established a covenant with Noah and all living creatures, entrusting humanity with responsibility for the world.
Generations later, Moses spent 40 days on Mount Sinai receiving the Torah. Yet while he was on the mountain, the Israelites built the Golden Calf, revealing that witnessing miracles did not mean they were ready to live by G-d’s covenant.
Later, the Israelites spent 40 years in the wilderness, learning to move from dependence on G-d toward responsibility and partnership with G-d.
The 40 days of the flood protected the possibility of life. The 40 years in the wilderness prepared a people to live with purpose.
This got me thinking about the last 40 years of Jewish life and what G-d may be teaching us now.
In 1986, much of the Jewish community was consumed by questions of continuity. Assimilation and intermarriage were viewed as existential threats. We feared that as Jews became more accepted into the broader world, we would eventually disappear into it.
In many ways, we responded by building our own arks, institutions and boundaries designed to protect Jewish identity and preserve what previous generations had entrusted to us. Those arks served an important purpose. But perhaps we sometimes confused protecting Jewish life with keeping it safely inside.
Over these decades, our communities became more diverse, richer, and in many ways stronger as we welcomed people who chose Judaism, embraced partners committed to Jewish life, and celebrated families raising Jewish children. We discovered that opening our doors could deepen belonging and strengthen our future.
Yet assimilation carried another promise: that acceptance meant we could finally be like everyone else, that our differences and particular responsibilities might no longer matter as much.
Jewish history has reminded us otherwise.
The liberation of Soviet Jewry, the flourishing of Jewish life in Israel, and extraordinary Jewish creativity expanded our possibilities. Yet rising antisemitism, divisions within our people, and October 7 have reminded us that Jewish peoplehood is more than an identity we celebrate. It is a responsibility we carry together.
Perhaps the lesson of these 40 years is that we cannot build a Jewish future by remaining inside the ark, nor can we forget who we are when we step outside it.
I see this tension and possibility in our work at the JCC every day. We are rooted in Jewish values, traditions and practice while welcoming people of different backgrounds, identities, and experiences. Our challenge is not simply to open our doors, but to create meaningful connections that strengthen both Jewish belonging and the broader community.
Noah’s covenant embraced all humanity and all of creation. At Sinai, the Jewish people accepted particular responsibilities. These covenants remind us that our responsibility to the Jewish people and our responsibility to the wider world need not compete. They can deepen one another.
What strikes me most about 40 is that transformation is never the end of the story. Noah must leave the ark. Moses must bring Torah down from the mountain. The Israelites must enter the land.
The miracle is no longer simply what G-d does for us. It becomes what we, inspired by G-d, are willing to do for one another.
Perhaps, like Noah, G-d is not asking us to rebuild the world exactly as it was before the flood, but to carry forward what is sacred from our past while having the courage to imagine what comes next. Noah did not leave the ark empty-handed, and neither do we. We carry generations of wisdom, tradition, and resilience. Our strength comes from honoring our roots while opening our hearts and minds to the broader world, recognizing that each makes us stronger.
May we have the wisdom to know when to hold tightly to what we have inherited, when to open ourselves to new possibilities, and how to create space for both.
