 One proposal places Rephidim in the Wadi Feiran, near its junction with the Wadi esh-Sheikh.When they leave Rephidim, the Israelites advance into the Sinai Wilderness, possibly marching through the passes of the Wadi Solaf and the Wadi esh-Sheikh, which converge at the entrance to the er-Rahah plain (which would then be identified with the "Sinai Wilderness"), which is three kilometers long and about eight hundred metres wide.See also Meribah.
