When Moses stood before Israel at Sinai and "took the book of the covenant and read it in the ears of the people" (Exodus 24:7), a question immediately arises: what exactly did he read? The Torah does not specify which text Moses held in his hands. The Mekhilta preserves a remarkable answer from Rabbi Yishmael ben Rabbi Yossi: Moses read everything from the beginning of creation until that moment.
Think about what this means. Before the people of Israel formally accepted the covenant at Sinai, Moses read them the entire narrative of the world: the creation of heaven and earth, Adam and Eve in the Garden, the Flood, the Tower of Babel, the calling of Abraham, the descent into Egypt, the plagues, the exodus, the crossing of the sea. All of it. Every story, every genealogy, every divine promise and human failure, from (Genesis 1:1) to the moment they stood at the foot of the mountain.
The implication is profound. Israel did not accept the covenant blindly. They heard the full record of God's relationship with humanity before they said "we will do and we will hear." They knew about Adam's sin, Noah's flood, and Abraham's trials. They understood the pattern: God offers a covenant, humans fail, God persists. And knowing all of this, knowing the full weight of what they were taking on, they accepted anyway. The "book of the covenant" was not a contract. It was a history, and Israel signed up with full knowledge of every chapter that came before.
