A moment of national crisis brings the Israelites together with exceptional unity and a shared sense of purpose. A severe and disgraceful act has been committed, prompting the entire nation to mobilize for war. The people gather with a firm, absolute resolve to respond to this outrage and punish those responsible.
As the nation mobilizes, there are different perspectives on exactly where this massive gathering takes place. One understanding is that the Israelites march directly to the city of Gibeah to confront the issue at its source [מצודת דוד]. Another approach suggests that the initial assembly happens in the city of Mizpah. In this view, Mizpah serves as a staging ground where the people wait to prepare their military provisions and dispatch messengers before advancing [מלבי״ם].
Regardless of the exact location, the atmosphere among the people is defined by complete agreement and deep solidarity. The entire nation stands together as equals, entirely united in a single plan of action. They bind themselves together with a shared purpose: to avenge the disgraceful deed and ensure that justice is served upon the perpetrators [רד״ק].
