We have arrived. All of the stories; all the of the generations between Adam and Eve, and the matriarchs and patriarchs; and 400 years of slavery in Egypt now culminate in the Israelites’ triumphant redemption. They all lead to this singular moment: the Revelation at Sinai. In Parashat Yitro, Moses guides the Israelite people to Mt. Sinai where they encounter God, experiencing all the drama and glory of Revelation.
Biblical commentators consistently note that one of the exceptional aspects of the Revelation at Sinai is that it is a communal revelation. Every previous moment of revelation in the Torah consists of God speaking privately to an individual or two — Noah, Abraham, Moses, and so on. Private revelation is the most common in other religions as well: an individual experiences God and then shares that revelation more broadly.
At Mount Sinai God was pleased to hear the vast multitude of diverse Israelites say in one united voice: “All that the Eternal has spoken we will do!” (Exodus 19:8) and God wanted additional assurance that they would follow through on this commitment. God told them: “I require worthy guarantors that you will observe Torah.” And the people of Israel replied: “Sovereign of the Universe, our ancestors will be our guarantors.” God was unimpressed. “Your guarantors need guarantors themselves, for they have not been without fault,” said Adonai. And so they responded: “Our prophets will guarantee it.” God retorted: “I have found fault with them also.” Thus the people offered this pledge: “Let our children be our guarantors.” And with a smile God concurred: “These are excellent guarantors, because of them I will give it to you” (Shir HaShirim Rabbah 1:4). The b’rit, “covenant,” advances and Torah is revealed.
