I am this day weak - Had Abner lived, all the tribes of Israel would have been brought under my government.

Though anointed king - I have little else than the title: first, having only one tribe under my government; and secondly, the sons of Zeruiah, Joab and his brethren, having usurped all the power, and reduced me to the shadow of royalty.

The Lord shall reward the doer of evil - That is, Joab, whom he appears afraid to name.

We talk much of ancient manners, their simplicity and ingenuousness; and say that the former days were better than these. But who says this who is a judge of the times? In those days of celebrated simplicity, etc., there were not so many crimes as at present I:grant: but what they wanted in number they made up in degree: deceit, cruelty, rapine, murder, and wrong of almost every kind, then flourished. We are refined in our vices; they were gross and barbarous in theirs: they had neither so many ways nor so many means of sinning; but the sum of their moral turpitude was greater than ours. We have a sort of decency and good breeding, which lay a certain restraint on our passions, they were boorish and beastly, and their bad passions were ever in full play. Civilization prevents barbarity and atrocity; mental cultivation induces decency of manners: those primitive times were generally without these. Who that knows them would wish such ages to return?

And I am this day weak, though anointed king,.... Which seems to be given as a reason, or for an excuse why he did not inflict just punishment upon the murderer, according to the law of God, because he was "weak"; not in body or mind, but with respect to the kingdom, that was like a tender branch, or in its infant state; and great care and caution were to be used that it was not overturned: he was a king by unction, not by birth; a son of the late king was yet up against him, and was possessed of the far greater part of the kingdom; he was indeed anointed by Samuel to be king over all Israel; but as yet he was not put into the possession of the kingdom he was anointed to; he was anointed and made king over Judah, and invested with the office of king there, and settled in it; and yet his power was not very great there, for as follows:

and these men, the sons of Zeruiah, be too hard for me; his sister's sons, Joab and Abishai, they were a check upon him; he could not do what he would, their influence was so great, both in the court and in the camp; the one was general of the army, and the other a considerable officer in it, and both variant men, and very respectable among the people, for their achievements in war, and the success they had; so that they were very much out of the reach of David to bring them to justice, without shaking his kingdom; and therefore in point of prudence he thought it best to connive at this fact until he was more established in the kingdom. Whatever may be said for this conduct, it is certain he was too dilatory, and which did not sit easy upon his mind, and therefore gave it in charge to Solomon before his death not to suffer Joab to go to his grave in peace, 1 Kings 2:5. Some take these words, "weak" and "hard", in a different sense, that David was weak or "tender" (x), as it may be rendered, tenderhearted, of a merciful disposition, and therefore spared Abner when he was in his hands, though he had done him so much harm, who was the Lord's anointed; but these men, his sister's sons, were of cruel tempers, more unmerciful than he, and therefore slew him; but the first sense seems best:

the Lord shall reward the doer of evil according to his wickedness; which may be considered either as an imprecation of evil on Joab, or a prediction, that sooner or later righteous judgment would be rendered to him by the Lord; with whom he leaves it to take vengeance on him, satisfying himself with this for the present, that though it was not in his power to do it, the Lord would in his own time and way: but after all that can be said in favour of David, he seems to have been too much in fear of men, and too distrustful of the power and promise of God to establish him in his kingdom, and was too negligent of public justice; which had it been exercised, might have prevented other sins, as the murder of Ishbosheth, to which the authors of it might be encouraged by this lenity.

(x) "tener", Pagninus, Montanus.

And I am this day weak, though anointed king; and these men the sons of Zeruiah be too hard for me: the LORD shall reward the doer of evil according to his wickedness.

3:39 Weak - In the infancy of my kingdom, not well settled in it. The metaphor is taken from a young and tender child or plant. These men - Joab and Abishai, the sons of thy sister Zeruiah. Too hard - That is, too powerful. They have so great a command over all the soldiers, and so great favour with the people, that I cannot punish them without apparent hazard to my person and kingdom; especially, now when all the tribes, except Judah, are in a state of opposition against me. But although this might give some colour to the delay of their punishment, yet it was a fault that he did not do it within some reasonable time, both because this indulgence proceeded from a distrust of God's power and faithfulness; as if God could not make good his promise to him, against Joab and all his confederates; and because it was contrary to God's law, which severally requires the punishment of willful murderers. It was therefore carnal wicked policy, yea cruel pity that spared him. If the law had had its course against Joab, it is probable the murder of Ishbosheth, Ammon, and others, had been prevented. So truly was he in these, and some other respects, a bloody man, which may be observed to the glory of the Divine grace, in his forgiveness and conversion.

weak: Heb. tender

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.
