Bullinger's massive classifications of figures of speech used in the Bible provides a wealth of help in interpretation. When I am studying a difficult verse, I often use the 'Scripture index' in Bullinger's work to find out if figurative language might come into play. Not only does Bullinger address figures that we commonly think of (exaggeration/hyperbole, etc.), but he divides them into subcategories - and includes classifications of figures one would not ordinarily detect through a casual reading of Biblical texts.
