Exodus 14:1-4

And the LORD spake unto Moses, saying, Speak unto the children of Israel, that they turn and encamp before Pi-hahiroth, between Migdol and the sea, over against Baal-zephon: before it shall ye encamp by the sea. For 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, that he shall follow after them; and I will be honoured upon Pharaoh, and upon all his host; that the Egyptians may know that I am the LORD. And they did so.
