Dr. Provan has written a well-researched and accessible expository commentary that gives intriguing and applicable insights.
I particularly enjoyed the excurses on explaining the symbols and imagery in Kings when read in canocial context; it is always good to keep in mind how the characters in Kings finds parallel in prior figures (David, Saul, Moses, Aaron, Joshua etc.) and later figures (particular Jesus) and how it has been interpreted in the Christian tradition over time.
The book also lays out a theological framework on how one is to measure the various kings based on what is stated in Deuteronomy and discussion on the tension between law vs. grace (conditionality of the covenants?), which is helpful.
