The first seven verses of Exodus 17 give readers the story of the water from the rock at Rephidim. The story is straightforward enough. Moses strikes the rock as God instructs him (Exod 17:6) and God provided water in the desert wilderness for the Israelites to drink. Moses calls the place “Massah and Meribah” (Exod 17:7) which produces the point of orientation for this episode, and sets up Part 2. The item that unites the two parts is that this incident (Massah and Meribah) is associated elsewhere in Scripture with Kadesh. Since the location of Kadesh is known, this incident is part of the problem of the location of Mount Sinai (especially for the Midian view) and links this incident to the failure with the giant clans from Numbers 13 (Part 2).
