Following the overwhelming experience of divine revelation, a profound shift occurs within the Israelite camp. Initially eager to receive the Torah directly from God without any human mediator, the people suddenly realize the true weight of such an encounter. Immediately after hearing the Ten Commandments, the priests and tribal leaders approach Moses in a state of panic [אבן עזרא, ביאור יש״ר, קאסוטו]. They recognize that they are spiritually unprepared for such an elevated experience and fear they might be physically harmed by it [מלבי״ם, העמק דבר]. Nevertheless, the direct revelation has already achieved its primary purpose. It provides undeniable proof to the entire nation that God speaks to humans, permanently preventing any future accusation that Moses invented the laws himself [רש ר הירש].
In their plea for Moses to act as a go-between, the Israelites declare their absolute willingness to obey. They make it clear that they are not rejecting the Torah. On the contrary, they promise to gladly accept and follow whatever Moses tells them, treating his instructions as if they came directly from God [רלב״ג, ביאור יש״ר]. The primary approach among commentators is that the people present a highly logical argument: since they are fully prepared to accept the commandments through Moses, there is no reason to continue risking their lives [אור החיים]. They know they can comfortably hear and understand a human voice, whereas if God continues to speak directly, they might die before they can even process the instructions [אור החיים]. Had they not made this request, God would have continued to deliver all the commandments and the entire Written Torah directly to the whole nation [רשב״ם, העמק דבר].
The terror gripping the camp is deeply rooted in the overwhelming sensory display of lightning, fire, and the miraculous divine voice [רלב״ג, חזקוני]. Their fear of death is entirely tangible. With every word spoken by God, the Israelites feel their souls leaving their bodies, and they understand that they cannot rely on a continuous miracle to survive such immense power [מלבי״ם]. Knowing that Moses will now speak to the massive camp, they also ask for a practical miracle. They hope God will amplify Moses's human voice so that every person can hear him clearly, which will serve as ongoing proof that he speaks on God's mission [אלשיך].
Beyond physical survival, there is a deeper layer to their fear. The direct communication from God completely cleanses the people of their natural human drives, effectively erasing their free will. The Israelites are terrified of this specific kind of death to their human essence. They recognize that genuine service to God is meant for human beings who struggle and make choices, not for flawless angels who lack free will [פרדס יוסף]. Acknowledging that only Moses possesses the spiritual endurance and preparation required for direct prophecy, they ask to be completely removed from the divine dialogue. They seek to step back entirely from the fire and the cloud, establishing Moses as the sole mediator between themselves and God [רמב״ן, רקנאטי, ביאור יש״ר].
