Exodus 14:28-31

Then 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. But the children of Israel had walked on dry land in the midst of the sea, and the waters were a wall to them on their right hand and on their left. So the LORD saved Israel that day out of the hand of the Egyptians, and Israel saw the Egyptians dead on the seashore. Thus Israel saw the great work which the LORD had done in Egypt; so the people feared the LORD, and believed the LORD and His servant Moses.
