On the goal of Exodus:
The goal of Exodus is thus the building of the Edenic sanctuary so that the Lord can dwell with his people, just as he once was Yahweh Elohim to the first human beings (100)
On the significance of Sinai:
After the exodus narrative the Israelites move to Mount Sinai. Mount Sinai stands in the way of Canaan, the land of their inheritance, but it is certainly no diversion, nor is it incidental. The centrality of the this mountain is shown by a number of narrative signals. First and most obvious is the virtual suspension of narrative pace. Israel stays at Sinai for eleven months in real time (Exod. 19:1-Num. 10:11) and fifty-seven chapters in narrative time. This is important given the fact that sixty-eight chapters precede Sinai and fifty-nine chapters follow-it. Sinai is central to the Torah. (100)
On the Sabbath:
Just as the covenant with Noah had a visible sign in the created order, and the covenant with Abraham a visible sign in the human body of the male, so the Sinai covenant has sign to be made visible in time. More significantly, this shows that the covenant at Sinai marks a people that manifests God’s intentions for creation from the beginning: the rule of God. Just as the Sabbath was a sign of God’s rule at creation, so it becomes a sign of his rule in history. There is significant progression here: the stability of the world order, the blessing of descendents, human activity mirroring divine activity. This is a noteworthy expression of rulership and dominion in history. Created order leads to descendents who exercise dominion. Just as the divine ruler worked and rested, human beings are to work and rest. This kingdom of priests is to manifest God’s rule to the world. (102-103)
