Rephidim

This episode is described in the Book of Exodus. The Israelites under Moses have come from the Wilderness of Sin. At Rephidim, they can find no water to drink, and angrily demand that Moses give them water. 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. He names the place Massah and Meribah (meaning "testing" and "quarreling"). In the Book of Numbers a similar event is described as taking place near Kadesh. Afterwards, the Amalekites attack the Israelites encamped at Rephidim, but are defeated. The Israelites are led in the battle by Joshua, while Moses, Aaron and Hur watch from a nearby hill. Moses notices that when his arms are raised, the Israelites gain the upper hand, but when they are down, the Amalekites prevail.
