Exodus 14:27-28

27And Moses stretched out his hand over the sea; and when the morning appeared, the sea returned to its full depth, while the Egyptians were fleeing into it. So the Lord overthrew the Egyptians in the midst of the sea.

28Then the waters returned and covered the chariots, the horsemen, and all the army of Pharaoh that came into the sea after them. Not so much as one of them remained.
