Exodus 14:1-4

And Jehovah spake unto Moses, saying, Speak unto the children of Israel, that they turn back and encamp before Pi-hahiroth, between Migdol and the sea, before Baal-zephon: over against it shall ye encamp by the sea. And Pharaoh will say of the children of Israel, They are entangled in the land, the wilderness hath shut them in. And I will harden Pharaoh’s heart, and he shall follow after them; and I will get me honor upon Pharaoh, and upon all his host: and the Egyptians shall know that I am Jehovah. And they did so.
