Exodus 14:10-12

10And Pharaoh approached; and the children of Israel lifted up their eyes, and behold, the Egyptians marched after them; and the children of Israel were much afraid, and cried out to Jehovah.

11And they said to Moses, Is it because there were no graves in Egypt, thou hast taken us away to die in the wilderness? why hast thou done this to us, that thou hast led us out of Egypt?

12Is not this what we told thee in Egypt, when we said, Let us alone, and we will serve the Egyptians? For [it had been] better for us to serve the Egyptians than to die in the wilderness.
