2 Samuel 3:26-27 ▼

26 Then Joab came out from David and sent messengers after Abner, and they brought him back from the well of Sirah; but David did not know it.

27 So when Abner returned to Hebron, Joab took him aside into the middle of the gate to speak with him privately, and there he struck him in the belly so that he died on account of the blood of Asahel his brother.
