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 Abner then said, "I'm ready. Let me go now to rally everyone in Israel for my master, the king. They'll make a treaty with you, authorizing you to rule them however you see fit." Abner was sent off with David's blessing.

22 Soon after that, David's men, led by Joab, came back from a field assignment. Abner was no longer in Hebron with David, having just been dismissed with David's blessing.

23 As Joab and his raiding party arrived, they were told that Abner the son of Ner had been there with David and had been sent off with David's blessing.

24 Joab went straight to the king: "What's this you've done? Abner shows up, and you let him walk away scot-free?

25 You know Abner son of Ner better than that. This was no friendly visit. He was here to spy on you, figure out your comings and goings, find out what you're up to."
