“Rephidim ” means
Rephidim : (Exodus 17:1,8; 19:2) The name means rests or stays , i.e. resting places. The place lies in the march of the Israelites from Egypt to Sinai. Its site is not certain, but it is perhaps Wady Feiran , a rather broad valley about 25 miles from Jebel Musa (Mount Sinai). Others place it in Wady es Sheikh , an eastern continuation of Feiran, and about 12 miles from Sinai. Here the Israelites fought their first battle and gained their first victory after leaving Egypt, the Amalekites having attacked them; here also the people murmured from thirst, and Moses brought water for them out of the rock. From this murmuring the place was called "Massah" and "Meribah."
