33 Then the king sang this tribute to Abner: Can this be? Abner dead like a nameless bum? 34 You were a free man, free to go and do as you wished - Yet you fell as a victim in a street brawl. And all the people wept - a crescendo of crying! 35 They all came then to David, trying to get him to eat something before dark. But David solemnly swore, "I'll not so much as taste a piece of bread, or anything else for that matter, before sunset, so help me God!" 36 Everyone at the funeral took notice - and liked what they saw. In fact everything the king did was applauded by the people. 37 It was clear to everyone that day, including all Israel, that the king had nothing to do with the death of Abner son of Ner. 38 The king spoke to his servants: "You realize, don't you, that today a prince and hero fell victim of foul play in Israel?

(Read 2 Samuel 3:22-39)
Judgments are prepared for such scorners as Abner; but Joab, in what he did, acted wickedly. David laid Abner's murder deeply to heart, and in many ways expressed his detestation of it. The guilt of blood brings a curse upon families: if men do not avenge it, God will. It is a sad thing to die like a fool, as they do that any way shorten their own days, and those who make no provision for another world. Who would be fond of power, when a man may have the name of it, and must be accountable for it, yet is hampered in the use of it? David ought to have done his duty, and then trusted God with the issue. Carnal policy spared Joab. The Son of David may long delay, but never fails to punish impenitent sinners. He who now reigns upon the throne of David, has a kingdom of a nobler kind. Whatever He doeth, is noticed by all his willing people, and is pleasing to them.
