Nijay Gupta's "Hidden Gems" Commentaries
This list includes the NT resources (mostly commentaries, but occasionally other kinds of relevant works) that Nijay K. Gupta has classified as "hidden gems"—that is, valuable and insightful sources typically overlooked or forgotten by others, often because they are stand-alone volumes published outside of major commentary series. Gupta identifies these works and offers brief comments on them in his New Testament Commentary Guide. Used by permission from Lexham Press. This collection has 37 books in 21 categories.
