I've been doing a bunch of reading on Messianism in early Jewish sources, including the Dead Sea Scrolls. I've mostly been looking for oblique information about the Jewish concept of "The world to come" around the time of Christ, but unfortunately haven't found much on that topic through these readings.
I did find an odd factoid in my reading yesterday I thought I'd pass along. According to James M. Scott, the Greek word meaning "lead in triumphal procession" in 2 Cor 2:14 can only refer to celebratory "victory lap" of sorts a conquering war general or leader makes after taking a city, in which the person being led (the object of the verb) is always the enemy prisoners of war, who are then executed at the end of the celebration.
If this is what is intended, which I am not necessarily advocating, it is an interesting method for Paul to both present himself as humbled (a former enemy of God) and special enough to deserve such treatment...and of course foreshadows his later martyrdom.
