יהושע, פרק כ״ב, פסוק י״ח

A wrongful act committed by a segment of society can carry an existential threat for an entire nation. Driven by a profound fear of collective punishment, representatives of the Israelites confront the tribes of Gad, Reuben, and half of Manasseh, explaining why they feel an absolute duty to intervene in their affairs. The representatives accuse these tribes of turning their backs on God [ביאור שטיינזלץ].

They warn of two destructive consequences stemming from this behavior. The first is immediate, as the tribes are actively rebelling against God in the present moment [מלבי״ם]. The second consequence is future and widespread, threatening to bring God's anger upon the entire nation [ביאור שטיינזלץ]. The timeline for this future threat is not the literal next day, but rather an impending time when punishment will ultimately be delivered [מצודת ציון, מצודת דוד], or a sign that the divine anger will endure for many days [מלבי״ם].

There are a few reasons why the offense of one group can spark anger against the whole community. One perspective roots this in mutual responsibility and national unity. Because the people are intricately bound together, the sins of a few cause God to remove His protection from the entire group. This mirrors past tragedies, such as the sin of Achan or the incident at Baal Peor, where a small group sinned but a plague struck everyone [רלב״ג, ביאור שטיינזלץ]. Furthermore, there is a real danger that such behavior will set a precedent, tempting other parts of the nation to learn from the sinners and join the rebellion [רלב״ג].

Another perspective emphasizes the strict duty to protest wrongdoing. The entire nation risks future punishment simply for remaining silent while others sin. By confronting the tribes, the representatives make it clear that they are innocent of this wrongdoing and feel compelled to speak out immediately to save themselves from any resulting penalty [מצודת דוד]. Ultimately, the actions of these tribes amount to much more than a rebellion against God. They represent a rebellion against the rest of the people, who stand to suffer the consequences, as well as a defiance of the central authority of the Great Sanhedrin, to which all the tribes are subject [רלב״ג].
