So Joab went to the king and said, “What have you done? Abner ¹  has come to you! Why would you send him away? Now he’s gone on his way! ² 

Then Joab left David and sent messengers after Abner. They brought him back from the well of Sirah. (But David was not aware of it.)

When David later heard about this, he said, “I and my kingdom are forever innocent before the Lord of the shed blood of Abner son of Ner!

All the people and all Israel realized on that day that the killing of Abner son of Ner was not done at the king’s instigation. ¹ 

Abner said to him, “Turn aside to your right or to your left. Capture one of the soldiers ¹  and take his equipment for yourself!” But Asahel was not willing to turn aside from following him.

But Asahel ¹  refused to turn aside. So Abner struck him in the abdomen with the back end of his ²  spear. The spear came out his back; Asahel ³  collapsed on the spot and died there right before Abner. ⁴  Everyone who now comes to the place where Asahel fell dead pauses in respect. ⁵ 

So Joab and Abishai chased Abner. At sunset they came to the hill of Ammah near Giah on the way to the wilderness of Gibeon.

Then Abner called out to Joab, “Must the sword devour forever? Don’t you realize that this will turn bitter in the end? When will you tell the people to turn aside from pursuing their brothers?”

Then Abner sent messengers ¹  to David saying, “To whom does the land belong? Make an agreement ²  with me, and I will do whatever I can ³  to cause all Israel to turn to you.”

You know Abner the son of Ner! Surely he came here to spy on you and to determine when you leave and when you return ¹  and to discover everything that you are doing!”

When Abner returned to Hebron, Joab took him aside at the gate as if to speak privately with him. Joab then stabbed him ¹  in the abdomen and killed him, avenging the shed blood of his brother Asahel. ² 

David instructed Joab and all the people who were with him, “Tear your clothes! Put on sackcloth! Lament before Abner!” Now King David followed ¹  behind the funeral bier.

So David issued orders to the soldiers and they put them to death. Then they cut off their hands and feet and hung them ¹  near the pool in Hebron. But they took the head of Ish-bosheth ²  and buried it in the tomb of Abner ³  in Hebron. ⁴
