As God’s people leave the Red Sea and journey into the wilderness, they become thirsty and they cannot find water. They travel on, beginning to be hungry, and realize they also lack food. Still further, they face another lack of water. The way the Israelites respond to these hardships is telling. God’s people have just seen the ten plagues that God brought against Egypt. With their own eyes they have watched the Red Sea give way to their crossing, and then drown the Egyptian army behind them. But only three days later, they lose faith in the God who provided them deliverance from slavery (Exodus 15:22).
