When Joab had come out from David, he sent messengers after Abner, and they brought him back from the well of Sirah; but David didn’t know it.
You know Abner the son of Ner. He came to deceive you, and to know your going out and your coming in, and to know all that you do.”
When Abner had returned to Hebron, Joab took him aside into the middle of the gate to speak with him quietly, and struck him there in the body, so that he died for the blood of Asahel his brother.
