According to Wikipedia, scientists are unanimous about Romans being written before Paul's imprisonment. But I just came across Romans 16:7:
Salute Andronicus and Junia, my kinsmen, and my fellowprisoners, who are of note among the apostles, who also were in Christ before me
Paul says "fellowprisoners"! Isn't it somehow indicative of Paul's imprisonment? Wikipedia says nothing about this verse, but I don't think scientists simply ignored it. Does anybody have some information on this point?
