Exodus 14:10-12

10As Pharaoh approached, the Israelites looked up and saw the Egyptians marching after them, and they were very frightened; so the Israelites cried out to the Lord.

11Then they said to Moses, “Is it because there are no graves in Egypt that you have taken us away to die in the wilderness? What is this that you have done to us by bringing us out of Egypt?

12Did we not say to you in Egypt, ‘Leave us alone; let us serve the Egyptians?’ For it would have been better for us to serve the Egyptians [as slaves] than to die in the wilderness.”
