19:1-8 To continue to lament for so bad a son as Absalom, was very unwise, and very unworthy. Joab censures David, but not with proper respect and deference to his sovereign. A plain case may be fairly pleaded with those above us, and they may be reproved for what they do amiss, but it must not be with rudeness and insolence. Yet David took the reproof and the counsel, prudently and mildly. Timely giving way, usually prevents the ill effects of mistaken measures.
7. Now … arise, go forth, and speak comfortably unto thy servants—The king felt the truth of Joab's reprimand; but the threat by which it was enforced, grounded as it was on the general's unbounded popularity with the army, showed him to be a dangerous person; and that circumstance, together with the violation of an express order to deal gently for his sake with Absalom, produced in David's mind a settled hatred, which was strongly manifested in his last directions to Solomon.
