Heat the oil in heavy large pot over medium-high heat. Sprinkle the beef with salt and pepper. Add half of the beef and cook until brown, about 8 minutes. Using a slotted spoon, transfer the beef to a bowl. Repeat with the remaining beef. Add the celery, carrots, onion, garlic, rosemary, and oregano to the pot. Sauté until the onions are translucent, about 8 minutes. Return the beef and any accumulated juices from the bowl to the pot. Add the broth and tomatoes with their juice. Bring the soup to a boil. Reduce the heat to medium-low. Cover and simmer until the meat is just tender, stirring occasionally, about 1 hour. Add the lentils. Cover and continue simmering until the lentils are tender, about 40 minutes. Stir in the parsley. Season the soup, to taste, with salt and pepper.
