(28) I and my kingdom are guiltless.--This was true. Joab's act was entirely without David's knowledge, and was not only against his will on moral grounds, but was in danger of proving disastrous to him politically; hence he takes the strongest means of showing his abhorrence of the deed.
Verse 28. - I and my kingdom are guiltless. By this David means, not his royal house, but the people generally, who too often have to pay the penalty for the sins of their rulers (see 2 Samuel 21:1). Necessarily this is the case, wherever the crime is a state crime; but David protests that Abner's murder was a private crime, for which Joab and Abishai alone ought to suffer.
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.
And afterward, when David heard it,.... That Joab had sent to fetch Abner back, and that he had stabbed him in the gate of the city, and he was dead; it was some time after it was done that the news of it was brought to David; this circumstance is observed, the more to clear the king from any concern in this affair:
he said; in a public manner, in open court, before all his princes; he called God to witness, and, as Josephus (i) says, stretching out his right hand to God, he cried aloud:
I and my kingdom are guiltless before the Lord for ever from the blood of Abner the son of Ner; he was sensible it would be known that Abner had been with him, and that Joab his general had killed him; and therefore it might be suspected that he had an hand in it, and that it was done by his order, with his privy council; and therefore, to purge him and them from it, he made this public declaration, that neither he nor his council knew anything of it; and that it was not done with their knowledge and consent, and by their order, but through the resentment of a single person; and therefore hoped that no man would impute the shedding of this blood unto them, or that God would punish them for it; and he was the rather led to make this public declaration, because he knew that the death of Abner in this way would be resented by the friends of Saul's family, and be an obstruction to the union of the two kingdoms, which it was known Abner was endeavouring to bring about.
