3 John 1:10

When I come. John intends to come personally and use his authority as an apostle to deal with Diotrephes (see Acts 13:10-12 and note). Everything he has done. Diotrephes: (1) would not pay attention to John's letter; (2) said terrible things about John (compare Jude 1:15) and told lies to cause trouble; (3) refused to receive the brothers and would give them no hospitality; (4) tries to drive out of the fellowship all who even admit they want to receive the brothers from John. [The present continuous implies that Diotrephes was trying to drive out those who wanted to receive the brothers. See Expositor's Greek Testament.]
