I was wondering if the 'community' had any recommendations on which 'preferred commentary' should be listed first in one's library. Granted that's going to come down to personal preference. But I'm hoping to glean some tips and recommendations to help me make that decision.
Theologically, I'm in the Protestant, Evangelical, Reformed section of Christianity. 
I was thinking it might be good to select a single volume or set that covered the entire Bible, so that when I'm first getting started, it would be consistent. Currently, I have the Bible Knowledge Commentary set as the first 'preferred commentary' but I'm wondering if there are suggestions for something better?
