Exodus 14:6

⁴And I will harden the heart of Pharaoh, and he shall pursue after them; and I will be glorified in Pharaoh, and in all his host, and all the Egyptians shall know that I am the Lord. And they did so.

⁵And it was reported to the king of the Egyptians that the people had fled: and the heart of Pharaoh was turned, and that of his servants against the people; and they said, What is this that we have done, to let the children of Israel go, so that they should not serve us?

— Exodus 14:6 —

⁷having also taken six hundred chosen chariots, and all the cavalry of the Egyptians, and rulers over all.

⁸And the Lord hardened the heart of Pharaoh king of Egypt, and of his servants, and he pursued after the children of Israel; and the children of Israel went forth with a high hand.
