22 Behold, the servants of David and Joab came from a foray, and brought in a great spoil with them: but Abner was not with David in Hebron; for he had sent him away, and he was gone in peace. 23 When Joab and all the army who was with him had come, they told Joab, saying, Abner the son of Ner came to the king, and he has sent him away, and he is gone in peace. 24 Then Joab came to the king, and said, “What have you done? Behold, Abner came to you. Why is it that you have sent him away, and he is quite gone? 25 You know Abner the son of Ner, that he came to deceive you, and to know your going out and your coming in, and to know all that you do.” 26 When Joab had come out from David, he sent messengers after Abner, and they brought him back from the well of Sirah; but David didn’t know it. 27 When Abner was returned to Hebron, Joab took him aside into the midst of the gate to speak with him quietly, and struck him there in the body, so that he died, for the blood of Asahel his brother. 28 Afterward, when David heard it, he said, “I and my kingdom are guiltless before Yahweh forever of the blood of Abner the son of Ner. 29 Let it fall on the head of Joab, and on all his father’s house. Let there not fail from the house of Joab one who has an issue, or who is a leper, or who leans on a staff, or who falls by the sword, or who lacks bread.” 30 So Joab and Abishai his brother killed Abner, because he had killed their brother Asahel at Gibeon in the battle. 31 David said to Joab, and to all the people who were with him, Tear your clothes, and gird yourselves with sackcloth, and mourn before Abner. King David followed the bier. 32 They buried Abner in Hebron: and the king lifted up his voice, and wept at the grave of Abner; and all the people wept. 33 The king lamented for Abner, and said, “Should Abner die as a fool dies? 34 Your hands were not bound, nor your feet put into fetters. As a man falls before the children of iniquity, so you fell.”
All the people wept again over him. 35 All the people came to cause David to eat bread while it was yet day; but David swore, saying, “God do so to me, and more also, if I taste bread, or anything else, until the sun goes down.” 36 All the people took notice of it, and it pleased them; as whatever the king did pleased all the people. 37 So all the people and all Israel understood that day that it was not of the king to kill Abner the son of Ner. 38 The king said to his servants, “Don’t you know that there a prince and a great man has fallen this day in Israel? 39 I am this day weak, though anointed king; and these men the sons of Zeruiah are too hard for me. May Yahweh reward the evildoer according to his wickedness.”

(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.
