2 Samuel 3:22-30

22Just then, David’s soldiers and Joab came from a raid, bringing with them much spoil. By then Abner was no longer with David in Hebron, for he had sent him away, and he departed in shalom.

23When Joab and all the soldiers with him arrived, they told Joab, saying, “Abner son of Ner came to the king, and he has sent him away, and he has gone in shalom.”

24Then Joab came to the king and said, “What have you done? Look here, Abner came to you—why did you send him away? Now he is getting away!

25You know Abner son of Ner—surely he came to deceive you, to spy on your goings and comings, and to find out all that you are doing.”

26When Joab left David, he sent messengers after Abner, so they brought him back from the well of Sirah, though David knew nothing about it.

27Now when Abner returned to Hebron, Joab took him aside within the gate to speak with him privately, and there stabbed him in the groin, so that he died—on account of the blood of his brother Asahel.

28When David heard about it afterward, he said, “I and my kingdom are innocent before Adonai forever from the blood of Abner son of Ner.

29May it whirl on Joab’s head and on all his father’s house. May the house of Joab never be without someone with discharge or tza'arat, lame or one fallen by the sword or one who lacks food.”

30So Joab and Abishai his brother killed Abner because he had killed their brother Asahel at Gibeon in battle.
