Exodus 14:1-8

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. And it was told the king of Egypt that the people were fled: and the heart of Pharaoh and of his servants was changed towards the people, and they said, What is this we have done, that we have let Israel go from serving us? And he made ready his chariot, and took his people with him: and he took six hundred chosen chariots, and all the chariots of Egypt, and captains over all of them. And Jehovah hardened the heart of Pharaoh king of Egypt, and he pursued after the children of Israel: for the children of Israel went out with a high hand.
