The story of Abraham pleading with God to spare Sodom and Gomorrah is more than just a negotiation; it’s a glimpse into the very nature of divine justice and collective responsibility.

We find ourselves in Genesis 18:32, where Abraham, ever the bargainer, is trying to save the cities from destruction. "Please, let my Lord not be incensed, and I will speak only this time. Perhaps ten will be found there." And God responds, "I will not destroy for the ten." But why ten? Why did Abraham stop there?

That's the question that Bereshit Rabbah 49 wrestles with. Why not nine? Or five? What's so special about the number ten?

One explanation, the text suggests, is the concept of an "assembly." In Jewish tradition, a group requires at least ten individuals to constitute a minyan, a quorum for communal prayer and other sacred acts. The idea here is that if ten righteous people could be found across those five doomed cities, they would form a kind of holy nucleus, a spiritual force strong enough to tip the scales. A group, the text says, is only called an assembly if it consists of ten individuals.

Another explanation casts our minds back to the Flood. Remember Noah? He and his family – eight souls in total – were spared, but their righteousness wasn't enough to save the rest of the world. So perhaps, the midrash suggests, ten represents a threshold, a minimal requirement for collective redemption.

There's also a more personal, almost heartbreaking, reason offered. Perhaps Abraham believed that ten righteous people already existed in Sodom: his nephew Lot, Lot's wife, their four daughters, and their four sons-in-law. He might have thought he was pleading for a group that already existed.

But the most striking interpretation comes from Rabbi Yehuda ben Rabbi Simon and Rabbi Ḥanin, in the name of Rabbi Yoḥanan. They make a distinction between Sodom and Jerusalem. Sodom needed ten. But Jerusalem? It only needed one! As Jeremiah 5:1 says, "Wander through the streets of Jerusalem…[if you will find [timtze’u] a man, if there is a performer of justice, a seeker of faithfulness, I will forgive it]." And Ecclesiastes 7:27 echoes, "One for one to find a tally."

Rabbi Yitzḥak takes this idea even further. How much is the minimum [mitzui] amount for one city? Jerusalem, he says. It is even one! As in, if even one righteous person could be found, justice would be deferred.

Think about that for a moment. One person. One act of kindness, one moment of truth, one spark of righteousness can be enough to hold back the tide.

What does this all mean for us? Perhaps it's a reminder that even in the darkest of times, individual actions matter. That even when faced with overwhelming negativity, the choice to be righteous, to seek justice, to embody faithfulness can have a profound impact. We may not be able to save the entire world, but maybe, just maybe, we can save our own little corner of it.
