Moses' return from Mount Sinai with the second set of tablets was a moment of profound awe. The radiant light glowing from his face created a sudden barrier of fear between him and the Israelites. This intense glow required a gradual process of calming and reconnection, beginning with the leadership and eventually extending to the entire nation.
Terrified by the divine light, the people had actually fled backward. They were struck with dread, believing that God's glory or His angels now rested upon Moses, and they feared that coming too close might harm them [רמב״ן]. To bridge this gap, Moses called out to the nation. He did so with deep humility and affection, showing no pride in his newly acquired honor [קאסוטו]. Once the people recognized his familiar voice, they understood it was still Moses and finally found the courage to approach [חזקוני, ביאור שטיינזלץ]. The very fact that they had to return proves they had initially run away in fear [אבן עזרא, חזקוני]. The first to step forward and gather around him were his brother and the community leaders [רש״י, ביאור יש״ר, ביאור שטיינזלץ].
Moses then spoke to them, though the exact words of this exchange are not immediately detailed. Commentators offer two main perspectives on the nature of this conversation. One view sees this as a specific, one time event where Moses spoke words of peace to ease their lingering fears. In this quiet moment, he shared the joyful news that God had forgiven them for the sin of the Golden Calf, that a new covenant had been made, and that he had brought down the new tablets [רמב״ן, העמק דבר, ביאור יש״ר, ביאור שטיינזלץ]. As he spoke, the people listened in absolute silence [העמק דבר], completely unharmed by the intense radiance of his face [חזקוני].
In contrast, the primary approach among commentators views the lack of specific details as a sign of an ongoing, daily routine rather than a single conversation [רש״י, הטור הארוך, מזרחי, שפתי חכמים, גור אריה, ברכת אשר]. Acting as God's messenger, Moses used this moment to establish a permanent system for teaching the Torah to the wilderness generation. Each day, he would first call upon Aaron and the leaders to instruct them. Afterward, the rest of the Israelites would gather to learn the laws in their presence [רש״ר הירש, שפתי חכמים, מזרחי]. Because it was impossible to teach the entirety of the Torah received at Sinai in a single day, this gradual, orderly transmission became his steady daily practice [גור אריה, קאסוטו].
