2 Samuel 3:26-27 ▼

26 When Joab left David, he sent messengers after Abner, and they brought him back from the well of Sirah; but David knew nothing [about Joab’s action].

27 So when Abner returned to Hebron, Joab took him aside to the middle of the gate to speak to him privately, and there he struck Abner in the abdomen so that he died, to avenge the blood of Asahel, Joab’s brother.
