2 Samuel 3:26-27

3:26 Then Joab left David and sent messengers after Abner. They brought him back from the well of Sirah. (But David was not aware of it.) 3:27 When Abner returned to Hebron, Joab took him aside at the gate as if to speak privately with him. Joab then stabbed him ¹  in the abdomen and killed him, avenging the shed blood of his brother Asahel. ² 

[3:27]  ¹ tn Heb “and he struck him down there [in] the stomach.”

[3:27]  ² tn Heb “and he [i.e., Abner] died on account of the blood of Asahel his [i.e., Joab’s] brother.”
