Exodus 15:22-27 - Yahweh Provides Water At Marah
22 Then Moses led Israel on from the Red Sea, and they went out to the Wilderness of Shur. They journeyed for three days in the wilderness without finding water. 23 They came to Marah, but they could not drink the water at Marah because it was bitter—that is why it was named Marah.
He made a statute and ordinance for them at Marah and He tested them there.
27 Then they came to Elim, where there were 12 springs of water and 70 date palms, and they camped there by the waters.
