UBS Dictionary of the Greek New Testament
verb
39.59 · Hostility, Strife · Conquer
to triumph over, to be completely victorious over (a figurative extension of meaning of θριαμβεύω ‘to lead prisoners of war in a victory procession,’ not occurring in the NT) to demonstrate one’s successful conquest of opposition Since the leading of prisoners of war in a victory procession is at the present time a relatively rare cultural phenomenon, it may be impossible to employ such a literal rendering of θριαμβεύω. One may, however, wish to employ a marginal note to indicate the background meaning of θριαμβεύω in this context.
39.60 · Hostility, Strife · Conquer
to cause to triumph to cause someone to completely triumph over In a number of languages it is difficult to speak of triumphing without indicating the goal of such an event, but in 2CO 2:14 there is no specified object over which triumph occurs. It is possible to introduce Satan as the one over whom the believer is victorious (see 2CO 2:11). However, it is also possible to understand θριαμβεύω in 2CO 2:14 as being essentially similar in meaning to θριαμβεύω[a] (39.59) and thus to translate 2CO 2:14 as ‘for in union with Christ we are always led by God as prisoners in Christ’s victorious procession.’
