What happened when the 430 years were completed and Israel gathered at Mount Sinai?

When the 430 years were completed and Israel gathered at Mount Sinai, God was preparing to do something totally different than He had ever done before: He would institute written commands and an organized system of worship, neither of which had existed from Genesis 1 until Exodus 20.

Les explains that Jacob ended up in Egypt with all his sons, and 215 years later they came out as 5, 6, 7 million souls. Another 215 years passed, and Moses led the children of Israel out of Egypt. When the 430 years were completed, the nation gathered around Mount Sinai, and God was getting ready to do something totally different than He had ever done before. From Genesis 1 until Exodus 20, there had been no written do’s and don’ts from God, and no single item of God instituted worship until this point. Les notes that while they probably brought sacrifices, there had been no organized system of worship.
