Col 3:19. Μὴ πικραἰνεσθε, be not bitter) Πικρία, hateful conduct (offensive behaviour) mixed with love. Many, who are polite to all abroad, notwithstanding without scruple treat their wives and children at home with covert bitterness, because they do not fear them; and when this feeling is vanquished, it affords a specimen of great softening of natural ruggedness of temper.
