Exodus 14:5-10

Then, of course, they accused Moses of not dealing with them fairly, murmured that he led them out of Egypt because had they not been right? They told him while they were still in Egypt, "Don't disturb things." This was just days after going out with a pretty high hand in the sight of all the Egyptians, joyful that they were going to freedom. So how quickly their faith evaporated when time began closing in on them. That was the real problem. Because there were the Egyptians, the horses, the chariots, all the shining army—all the might of Egypt represented there. Their backs were up against the sea and they could see the death sentence approaching them as fast as a horse could pull a chariot. Time—the end of their life was very quickly coming within view. So they thought that their lives were hanging in a balance when they saw the army.
