(24) What hast thou done?--Joab's somewhat rough remonstrance with David may have been supported by an honest suspicion of Abner, for which there was some ground in Abner's long opposition to the known Divine will and his present revolt from Ish-bosheth; but there was also a personal enmity, due partly to the fear of being himself supplanted by an older and famous warrior, and partly to the desire to revenge the death of his brother Asahel. Joab seeks to poison David's mind against Abner, that he may better carry out his revenge.

Verses 24, 25. - What hast thou done? David's secret dealing makes Joab see a personal wrong to himself in the negotiation with Abner. There could be no room, he feels, for both of them in David's army, and David meant, he supposes, to sacrifice himself. In hot haste, therefore, he rushes into the king's presence, and reproaches him for what he has done, but covers his personal feelings with professed zeal for his master's interests. Abner is a mere spy, who has come on a false pretext, and with the real intention of learning David's going out and coming in, that is, his present manner of life and undertakings. All that thou doest; literally, all that thou art doing; all that is now going on, and thy plans and purposes. Abner would not only judge by what he saw, but in his interview with David would lead him on to talk of his hopes and prospects. David had little time to explain the real object of Abner's coming, nor was Joab in a mood to listen to anything he said. He had detected his master in secret negotiations, and would regard his excuses as tainted with deceit. And after giving vent to his auger in reproaches, he hurried away to thwart David's plans by a deed of most base villainy. Had David acted openly, all would have been done with Joab's consent and approval.

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.Then Joab came to the king,.... To the apartment where he was; perhaps he was told the above at his first entering into the king's palace, by some in waiting, before he came to the king, which filled him with wrath, so that he came to him in a passion:

and said to him, what hast thou done? which was very insolent in a subject to say to his prince:

behold, Abner came unto thee; I have been credibly informed of it, and am assured it is a fact which cannot be denied; he represents it as if he had done a wrong thing to admit him to come to him; but perhaps the great fault was that he had let him go:

why is it that thou hast sent him away, and he is quite gone? or "going, is gone" (e); is clean gone off, when he ought to have been laid hold on as a traitor, and put in irons.
