Rephidim

Rephidim or Refidim (Hebrew: רְפִידִים) is one of the places visited by the Israelites in the biblical account of the Exodus from Egypt.

Moses, fearing they will stone him, calls on Jehovah for help and is told to strike a certain "rock in Horeb," in God's name which causes a stream to flow from it, providing ample water for the people.

[5] When they leave Rephidim, the Israelites advance into the Sinai Wilderness,[6] 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.

Wadi Feiran was an oasis, which would explain the battle with the Amalekites in terms of a struggle for control of water sources.

[5] Another proposed location for Rephidim is in northwestern Saudi Arabia north of the town of al-Bad, the ancient city of Midian.
