2 Samuel 3:22–30
22 Just then the servants of David arrived with Joab from a raid, bringing much spoil with them. But Abner was not with David at Hebron, for he had sent him away, and he had gone in peace. 23 When Joab and all the army that was with him came, it was told Joab, “Abner the son of Ner came to the king, and he has let him go, and he has gone in peace.” 24 Then Joab went to the king and said, “What have you done? Behold, Abner came to you. Why is it that you have sent him away, so that he is gone? 25 You know that Abner the son of Ner came to deceive you and to know oyour going out and your coming in, and to know all that you are doing.”
26 When Joab came out from David’s presence, he sent messengers after Abner, and they brought him back from the cistern of Sirah. But David did not know about it. 27 And when Abner returned to Hebron, Joab took him aside into the midst of the gate to speak with him privately, pand there he struck him qin the stomach, so that he died, for the blood of Asahel his brother. 28 Afterward, when David heard of it, he said, “I and my kingdom are forever guiltless before the Lord for the blood of Abner the son of Ner. 29 rMay it fall upon the head of Joab and upon all his father’s house, and may the house of Joab never be without sone who has a discharge or who is tleprous or who holds a spindle or who falls by the sword or who lacks bread!” 30 So Joab and Abishai his brother killed Abner, because uhe had put their brother Asahel to death in the battle at Gibeon.
