“They journeyed for three days in the wilderness without finding water . . . the people grumbled to Moses, ‘What are we going to drink?’” (Exodus 15:22-24)
Just before they grumbled about having no water in the dry desert, Miriam had led Israel in a hymn to the Lord for His miraculous deliverance. The song was, “Sing to the Lord for He is highly exalted; He has thrown the horse and its rider into the Sea” (15:21). This was the Red Sea the LORD had just divided, made dry land to appear in its midst, and used to swallow up every single one of their pursuing enemies. If God can make dry land to appear in the midst of water, why was it so hard to believe He could also make water appear in the midst of dry land? They eventually did come to water at Marah, but it was undrinkable.
