Luke 18:14

If any one should ask why the Pharisee is here condemned for speaking some few words in his own commendation, and why the like sentence was not passed on Job, who praised himself much more; the difference is evident: the former praised himself without any necessity, merely with an intention of indulging his vanity, and extolling himself over the poor publican; the latter, being overwhelmed with misery, and upbraided by his friends, as if, forsaken of God, he suffered his present distress in punishment of his crimes, justifies himself by recounting his virtues for the greater glory of God, and to preserve himself and others in the steady practice of virtue, under similar temptations. (Theophylactus)
