Exodus 14:29-31

But the people of Israel had walked through the middle of the sea on dry ground, as the water stood up like a wall on both sides. That is how the LORD rescued Israel from the hand of the Egyptians that day. And the Israelites saw the bodies of the Egyptians washed up on the seashore. When the people of Israel saw the mighty power that the LORD had unleashed against the Egyptians, they were filled with awe before him. They put their faith in the LORD and in his servant Moses.
