New Defender's Study Bible Notes
20:13 death and hell. “Death” is often taken as synonymous with “the grave” (e.g., I Corinthians 15:55), where dead bodies are confined, whereas “hell” (Greek hades) is the place where the souls of the dead are confined. Multitudes of dead bodies are in the sea, rather than in the earth, of course, especially the great numbers of people who perished in the Noahic Flood. The ashes of those bodies that have been cremated have found their way either to the earth or to the sea, and so are also included among either the dead in the sea or those in the ground. In any case, the dead bodies of the unsaved will all be raised, presumably in their old natural condition, and reunited with their souls from Hades, to go before God in judgment.
