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.
When Joab and all the host that was with him were come,.... To Hebron, or rather to David's court; for their coming to the city is before mentioned; this must be understood not of the whole army, of all the common soldiers, but of the chief officers, who with Joab came to court, to wait upon David, and report their success:
they told Joab, saying, Abner the son, of Ner came to the king; some of the courtiers informed him of it, who knew it would not be very agreeable to him:
and he hath sent him away, and he is gone in peace: instead of seizing him, and laying him in a prison as his enemy, he has let him go with all the marks of friendship and good will.
