 Wadi Feiran was an oasis, which would explain the battle with the Amalekites in terms of a struggle for control of water sources.Another proposed location for Rephidim is in northwestern Saudi Arabia near the town of al-Bad, the ancient city of Midian.Some researchers suggest that Mount Sinai was not in the Sinai Peninsula, but in Midian, which is modern-day Saudi Arabia, and subsequently place Rephidim here as well.
