🔼The name Rephidim in the Bible
Rephidim is a place where Israel camped and defeated the Amalekites (Exodus 17:8). At Rephidim Moses strikes a rock so that it gives water (Exodus 17:6), and names the place Massah and Meribah. He does the same thing again at another place called Meribah, but this time in anger (Numbers 20:12). Hence he only gets to view the Promised Land from Mount Abarim, but he is not allowed to enter.
