A.T. Robertson Commentary Matthew 5:10

"Blessed are they that have been persecuted for righteousness` sake: for theirs is the kingdom of heaven." — Matthew 5:10 (ASV)

That have been persecuted for righteousness' sake (ο δεδιωγμενο ενεκεν δικαιοσυνης). Posing as persecuted is a favourite stunt. The kingdom of heaven belongs only to those who suffer for the sake of goodness, not who are guilty of wrong.
