דברים, פרק כ״ז, פסוק י״א

As the Israelites stand on the brink of entering the promised land, Moses prepares them for a monumental ceremony of blessings and curses set to take place on Mount Gerizim and Mount Ebal. Having already designated the elders and priests as the guardians of the Torah, Moses now calls upon the entire nation to take an active, participatory role in the event.

The purpose of this nationwide involvement is for the people themselves to vocalize the blessings and curses. By doing so, they publicly declare that following the Torah is the fundamental requirement for their national survival and peace [רש ר הירש]. Furthermore, this mass participation serves to embed a deep awareness of God's constant supervision. Before the Israelites scatter to settle their individual plots of land, they must fully realize that God watches over even the most hidden actions, reaching places where human courts and justice systems cannot intervene [רש ר הירש].

The precise timing of these instructions carries great historical and practical weight. Chronologically, this moment marks the completion of Moses reviewing the Torah with the nation, the exact time they truly solidified their identity as a people [ברכת אשר על התורה]. Beyond the historical significance, there is a psychological strategy behind giving these directions at this exact moment. Moses needed to outline the arrangement of the tribes immediately to prevent any future complaints or resistance regarding who would be placed on the mountain of blessing and who would be sent to the mountain of curse. Because the people had just sworn to uphold the covenant and accepted its severe consequences, no one could object to their assigned location for the ceremony. Their fundamental agreement to the entire process had already been secured [שפתי כהן].
