26 And when Joab was come out from David, he sent messengers after Abner, who caused him to return from the well of Sirah, but David did not know it. 27 And when Abner had returned to Hebron, Joab took him aside in the gate to speak with him quietly and smote him there under the fifth rib that he died, for the blood of Asahel his brother. 28 And afterward when David heard it, he said, I and my kingdom are guiltless before the LORD for ever from the blood of Abner, the son of Ner. 29 Let it rest on the head of Joab and on all his father’s house and let there not fail from the house of Joab one that has an issue or that is a leper or that leans on a staff or that dies by the sword or that lacks bread. 30 So Joab and Abishai his brother slew Abner because he had slain their brother Asahel at Gibeon in the battle.
