Exodus 14:3-5

Darby Translation

³ And Pharaoh will say of the children of Israel, They are entangled in the land, the wilderness has hemmed them in.

⁴ And I will harden Pharaoh's heart, that he may pursue after them; and I will glorify myself in Pharaoh, and in all his host; and the Egyptians shall know that I am Jehovah. And they did so.

⁵ And it was told the king of Egypt that the people had fled; and the heart of Pharaoh and of his bondmen was turned against the people, and they said, Why have we done this, that we have let Israel go from our service?
