Exodus 14:7, 17, 28

and he took six hundred chosen chariots, and all the chariots of Egypt, and captains over every one of them.

And I, behold, I will harden the hearts of the Egyptians, and they shall follow them: and I will get me honour upon Pharaoh, and upon all his host, upon his chariots, and upon his horsemen.

And the waters returned, and covered the chariots, and the horsemen, and all the host of Pharaoh that came into the sea after them; there remained not so much as one of them.
