Exodus 14:29-31

But the Israelites crossed the sea on dry land, with a wall of water on their right and on their left. So that day the LORD saved the Israelites from the Egyptians, and the Israelites saw the Egyptians lying dead on the seashore. When the Israelites saw the great power the LORD had used against the Egyptians, they feared the LORD, and they trusted him and his servant Moses.
