Exodus 14:28-30

28The water flowed back and covered the chariots and horsemen—the entire army of Pharaoh that had followed the Israelites into the sea. Not one of them survived. 29But the Israelites went through the sea on dry ground, with a wall of water on their right and on their left. 30That day the LORD saved Israel from the hands of the Egyptians, and Israel saw the Egyptians lying dead on the shore.
