The waters flowed back and covered the chariots and horsemen—the entire army of Pharaoh that had chased the Israelites into the sea. Not one of them survived.
KJV
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.
ASV
And the waters returned, and covered the chariots, and the horsemen, even all the host of Pharaoh that went in after them into the sea; there remained not so much as one of them.
