Exodus 14:10-14

As 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. Then 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? Did 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.” Then Moses said to the people, “Do not be afraid! Take your stand [be firm and confident and undismayed] and see the salvation of the LORD which He will accomplish for you today; for those Egyptians whom you have seen today, you will never see again. The LORD will fight for you while you [only need to] keep silent and remain calm.”
