Moshe Appeals to Brotherhood to Unite Tribes for Battle in Biblical Lesson on War

War leaves deep psychological scars on those involved, often requiring mental health support for soldiers who face death and destruction. Despite the heavy personal costs, tens of thousands of Israeli fighters have continued to serve with dedication for over two and a half years. Psychologists and sociologists have debated what motivates individuals to risk their lives in war, considering factors such as legal obligation, social pressure, moral conviction, or lack of reflection on consequences.

The weekly Torah portion "Matot-Masei" highlights a related issue from biblical times, when representatives of the tribes of Reuben and Gad requested to remain east of the Jordan River instead of entering the Promised Land with the rest of the Israelites. Their reason was practical: the land was ideal for their livestock. Moses responded not with legal or divine threats but by appealing to their sense of brotherhood, famously asking, "Will your brothers go to war while you sit here?" He emphasized the emotional bond and solidarity expected among the tribes.

Initially, the tribes promised to join the battle and not claim their inheritance until the land was divided among all tribes. However, later the prophet Deborah recounted that the tribe of Reuben chose not to participate in a subsequent war, preferring to stay with their flocks. This confirmed Moses’ fears that without a natural feeling of brotherhood, agreements and conditions alone could not ensure unity.

The article draws a parallel to a personal story of a young man who gave up a long-awaited ski camp to attend a distant cousin’s wedding, understanding the importance of family despite personal disappointment. It argues that while laws and sanctions can be enacted to enforce military service, true brotherhood cannot be legislated or imposed. Instead, it must be cultivated daily through words, actions, and mutual care, starting with ourselves and those close to us.
