The Israelites come to Mt. Sinai, where God invites them into a covenant relationship. He wants to make them his representatives to all the nations and come to personally live in their midst. But Israel rebels, leading to making of the golden calf.
The collection of books from Genesis through Deuteronomy, also known as the Torah, tells the story of creation, the birth of the nation of Israel, and God's covenant with that nation after he saves that nation out of Egypt.
