2 Samuel 3:23

23 And Joab, and the hosts that were with him, came afterward; therefore it was told to Joab of tellers, (saying,) Abner, the son of Ner, came to the king, and the king let go him, and he went forth in peace. (And so Joab, and the men who were with him, came shortly thereafter; and people said to Joab, Abner, the son of Ner, came to the king, and the king let him go away, with a guarantee of safety.)

2 Samuel 3:23 Meaning and Commentary

2 Samuel 3:23

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.

2 Samuel 3:23 In-Context

21 And Abner said to David, I shall rise up, that I gather all Israel to thee, my lord the king, and that I make (a) bond of peace with thee, and that thou reign on all, as thy soul desireth. Therefore when David had led forth Abner, and he had gone in peace, (And Abner said to David, I shall rise up, and gather all Israel to thee, my lord the king, and they shall make a covenant with thee, and thou shalt reign upon all of them, as thy soul desireth. And after David had let Abner go away, with a guarantee of surety, or of safety,)

22 anon the servants of David and Joab came with a full great prey, when the thieves were slain; and Abner was not then with David, in Hebron, for David had let him go, and he went forth in peace. (shortly thereafter David's men and Joab came back from a raid, with a great deal of prey; and Abner was then not with David, in Hebron, for David had let him go away, with a guarantee of safety.)

23 And Joab, and the hosts that were with him, came afterward; therefore it was told to Joab of tellers, (saying,) Abner, the son of Ner, came to the king, and the king let go him, and he went forth in peace. (And so Joab, and the men who were with him, came shortly thereafter; and people said to Joab, Abner, the son of Ner, came to the king, and the king let him go away, with a guarantee of safety.)

24 And Joab entered to the king, and said, What hast thou done? Lo! Abner came to thee; why lettest go thou him (why hast thou let him go), and he went, and departed from thee?

25 Knowest thou not (that) Abner, the son of Ner, for hereto he came to thee, that he should deceive thee, and that he should know thy going out and thine entering, and should know all things which thou doest? (Thou must know that Abner, the son of Ner, came to thee so that he could deceive thee, and learn thy going out and thy coming in, and so know all the things that thou doest.)
