Take the story from Pirkei DeRabbi Eliezer, chapter 38 – it really brings this concept to life.

The passage begins with a stark reminder of consequences. Remember the men of Jabesh-Gilead? They didn't show up to the assembly, didn't stand with their community. And the price? According to the text, citing Judges 21:5, it was death. A heavy penalty indeed! It underscores just how seriously the community took collective participation.

But then, the narrative shifts, and we delve into the power of the ban – the ḥerem (חרם). Pirkei DeRabbi Eliezer uses the story of King Saul to illustrate this. Saul, son of Kish, issued a decree: everyone, young and old, had to fast. "Cursed be the man that eateth any food until it be evening" (1 Samuel 14:24), he proclaimed.

Now, Jonathan, Saul's son, hadn't heard about this decree. He innocently ate a bit of honey. And what happened? "His eyes were enlightened" (1 Samuel 14:27). A seemingly small act, but it had immediate, noticeable effects.

But here's where things get really interesting. Saul sees the Philistines coming, and he realizes something's amiss. Someone has transgressed the ban. How does he figure this out? The text describes twelve stones, presumably those representing the twelve tribes on the High Priest's breastplate. When a tribe followed the precepts, its stone shone brightly. But when a tribe faltered, its light dimmed.

Saul looks at these stones, and he sees that the tribe of Benjamin – his own tribe! – had violated the ban. So, he casts lots to find the guilty party. And who is revealed? Jonathan and Saul himself! “And Jonathan and Saul were taken” (1 Samuel 14:41).

Imagine the scene. Saul, in his zeal, draws his sword, ready to slay his own son! "God do so, and more also: for thou shalt surely die, Jonathan" (1 Samuel 14:44), he cries out. It’s a moment of intense drama, highlighting the almost terrifying power he believed the ban held.

But the people, wisely, intervene. "Our lord king! It is an error," they plead. They bring a burnt offering, a korban olah (קרבן עולה) on Jonathan's behalf, to atone for the mistake. And, as the text says, “So the people rescued Jonathan, that he died not” (1 Samuel 14:45).

What are we to make of this story? It’s not just a simple tale of a king and his son. It's a profound exploration of communal responsibility, the power of vows and bans, and the potential for both zealousness and forgiveness. It shows us the importance of community, and also the dangers of extremism. It’s a reminder that even leaders can err, and that sometimes, the wisdom of the many can save us from the mistakes of the few. Powerful stuff, right?
