“This magnificent poem [Exodus 15:1-21] has been much analyzed, dissected, scanned, and compared with an array of supposed precedent and counterpart works. It has been variously attributed and dated, and forced into a wide variety of forms and Sitze im Leben. There have been attempts to determine some parts of it as early and some parts as late, and to describe therefrom an evolution of both its form and its content. None of these attempts has been entirely successful. The best of them have amounted to no more than helpful suggestions, while the worst of them have been fiction bordering fantasy.”
