2 SAMUEL iii. 22-39; iv.
It is quite possible that, in treating with Abner, David showed too complacent a temper, that he treated too lightly his appearance in arms against him at the pool of Gibeon, and that he neglected to demand an apology for the death of Asahel. Certainly it would have been wise had some measures been taken to soothe the ruffled temper of Joab and reconcile him to the new arrangement. This, however, was not done. David was so happy in the thought that the civil war was to cease, and that all Israel were about to recognise him as their king, that he would not go back on the past, or make reprisals even for the death of Asahel. He was willing to let bygones be bygones. Perhaps, too, he thought that if Asahel met his death at the hand of Abner, it was his own rashness that was to blame for it. Anyhow he was greatly impressed with the value of Abner's service on his behalf, and much interested in the project to which he was now going forth--gathering all Israel to the king, to make a league with him and bind themselves to his allegiance.
In these measures Joab had not been consulted. When Abner was at Hebron, Joab was absent on a military enterprise. In that enterprise he had been very successful, and he was able to appear at Hebron with the most popular evidence of success that a general could bring--a large amount of spoil. No doubt Joab was elated with his success, and was in that very temper when a man is most disposed to resent his being overlooked and to take more upon him than is meet. When he heard of David's agreement with Abner, he was highly displeased. First he went to the king, and scolded him for his simplicity in believing Abner. It was but a stratagem of Abner's to allow him to come to Hebron, ascertain the state of David's affairs, and take his own steps more effectively in the interest of his opponent. Suspicion reigned in Joab's heart; the generosity of David's nature was not only not shared by him, but seemed silliness itself. His rudeness to David is highly offensive. He speaks to him in the tone of a master to a servant, or in the tone of those servants who rule their master. "What hast thou done? Behold, Abner came unto thee; why is it that thou hast sent him away, and he is quite gone? Thou knowest Abner the son of Ner, that he came to deceive thee, and to know thy going out and thy coming in, and to know all that thou doest." David is spoken to like one guilty of inexcusable folly, as if he were accountable to Joab, and not Joab to him. Of the king's answer to Joab, nothing is recorded; but from David's confession (ver. 39) that the sons of Zeruiah were too strong for him, we may infer that it was not very firm or decided, and that Joab set it utterly at nought. For the very first thing that Joab did after seeing the king was to send a message to Abner, most likely in David's name, but without David's knowledge, asking him to return. Joab was at the gate ready for his treacherous business, and taking Abner aside as if for private conversation, he plunged his dagger in his breast, ostensibly in revenge for the death of his brother Asahel. There was something eminently mean and dastardly in the deed. Abner was now on the best of terms with Joab's master, and he could not have apprehended danger from the servant. If assassination be mean among civilians, it is eminently mean among soldiers. The laws of hospitality were outraged when one who had just been David's guest was assassinated in David's city. The outrage was all the greater, as was also the injury to King David and to the whole kingdom, that the crime was committed when Abner was on the eve of an important and delicate negotiation with the other tribes of Israel, since the arrangement which he hoped to bring about was likely to be broken off by the news of his shameful death. At no moment are the feelings of men less to be trifled with than when, after long and fierce alienation, they are on the point of coming together. Abner had brought the tribes of Israel to that point, but now, like a flock of birds frightened by a shot, they were certain to fly asunder. All this danger Joab set at nought, the one thought of taking revenge for the death of his brother absorbing every other, and making him, like so many other men when excited by a guilty passion, utterly regardless of every consequence provided only his revenge was satisfied.
