Exodus 14:1-4

Then the LORD said to Moses, “Tell the Israelites to turn back and encamp near Pi Hahiroth, between Migdol and the sea. They are to encamp by the sea, directly opposite Baal Zephon. Pharaoh will think, ‘The Israelites are wandering around the land in confusion, hemmed in by the desert.’ And I will harden Pharaoh’s heart, and he will pursue them. But I will gain glory for myself through Pharaoh and all his army, and the Egyptians will know that I am the LORD.” So the Israelites did this.
