A pivotal moment marks the boundary between a long era of wandering and the great, direct march toward the Land of Israel [ביאור שטיינזלץ]. The period of punishment for the generation that left Egypt finally reaches its conclusion. At this stage, not a single individual destined to pass away due to the sin of the spies remains alive [ביאור יש״ר]. The men of war who perished were the military-aged men over twenty [רש״י], with some identifying them specifically as the group who had defiantly armed themselves to ascend the mountain against God's explicit command [חזקוני].
The timing of this transition is highly deliberate. The conquest of the lands east of the Jordan River could only begin now because these territories were destined to become part of the Land of Israel. Consequently, the campaign could not commence as long as anyone forbidden from entering the land was still alive [העמק דבר]. Furthermore, the delay honored Moses; if the people were to enter the land immediately upon the generation's passing, he would be left behind entirely alone [חזקוני]. The actual dying ceased on the ninth of Av, but the people only fully realized the decree was lifted on the fifteenth of Av, when the full moon confirmed their survival, transforming their days of mourning into immense joy [רבנו בחיי, אלשיך].
The end of this generational decree profoundly impacts the nature of Moses' prophecy. The close connection between the passing of the old generation and the renewal of divine communication highlights a fundamental principle: the Divine Presence rests upon prophets solely for the sake of the Israelites. For thirty-eight years, while the nation was under divine disfavor, God did not communicate with Moses in an intimate, face-to-face manner. Because a community's fate follows its majority, even a uniquely righteous leader like Moses suffered a diminished connection when the people were condemned to exile and death [רש״י, רבנו בחיי, תורה תמימה, דברי דוד]. During those years of divine anger, prophecy reached Moses only in night visions, through an angel, or when strictly necessary for urgent practical instructions [משכיל לדוד].
With the punishment complete, the prophetic connection returns to its full clarity and power. Previously, the communication between God and Moses was characterized by a softer, indirect, and sometimes less clear tone. Now, it shifts back to direct, face-to-face interaction with absolute clarity [גור אריה, רש ר הירש, רבנו בחיי]. Although this direct form of communication is often considered firmer and more severe, the primary approach among commentators is that this intensity actually stems from profound love and affection. Much like a parent disciplining a child or someone speaking firmly to a loved one to leave a lasting impression, God's direct communication signifies the restoration of an intimate, close relationship with Moses and the Israelites [כלי יקר, לבוש האורה, שפתי חכמים].
