Exodus 14:1-5

Now the Lord spoke to Moses, saying,

“Tell the sons of Israel to turn back and camp in front of Pi-hahiroth, between Migdol and the sea; you shall camp in front of Baal-zephon, opposite it, by the sea.

For Pharaoh will say of the sons of Israel, ‘They are wandering aimlessly in the land; the wilderness has shut them in.’

And I will harden Pharaoh’s heart, and he will chase after them; and I will be honored through Pharaoh and all his army, and the Egyptians will know that I am the Lord.” And they did so.

When the king of Egypt was told that the people had fled, Pharaoh and his servants had a change of heart toward the people, and they said, “What is this that we have done, that we have let Israel go from serving us?”
