Exodus 14:3-4

Then Pharaoh will think, ‘The Israelites are confused. They are trapped in the wilderness!’ And once again I will harden Pharaoh’s heart, and he will chase after you. I have planned this in order to display my glory through Pharaoh and his whole army. After this the Egyptians will know that I am the LORD!” So the Israelites camped there as they were told.
