Databases index journal articles as well as other materials which might include books, book chapters, dissertations, or conference proceedings.
Use the Scripture Citation Index in each of these databases to search for journal articles (and other materials) on particular Biblical books, chapters, and verses; note the Scriptures link in the blue navigation menu at the top of the search screen.
