Matthew 23:25-26

25“Woe to you, [self-righteous] scribes and Pharisees, hypocrites! For you clean the outside of the cup and of the plate, but inside they are full of extortion and robbery and self-indulgence (unrestrained greed).

26You [spiritually] blind Pharisee, first clean the inside of the cup and of the plate [examine and change your inner self to conform to God’s precepts], so that the outside [your public life and deeds] may be clean also.
