But he refused to turn aside. Therefore Abner struck him in the stomach with the butt of his spear, so that the spear came out at his back. And he fell there and died where he was. And all who came to the place where Asahel had fallen and died, stood still.
We have here the contest between Abner and Asahel. Asahel, the brother of Joab and cousin-german to David, was one of the principal commanders of David's forces, and was famous for swiftness in running: he was as light of foot as a wild roe (Sa2 2:18); this he got the name of by swift pursuing, not swift flying.
Commenting on 2 Samuel 2:18-24
Howbeit, he refused to turn aside,.... Determined on making him his captive if possible. Wherefore Abner, with the hinder end of the spear; he had in his hand, which seems to have had a pike at both ends; so that with the hinder end of it, next to Asahel, he thrust it at him, without turning to him: and smote him under the fifth rib...
Howbeit he refused to turn aside: wherefore Abner with the hinder end of the spear smote him under the fifth [rib], that the spear came out behind him; and he fell down there, and died in the same place: and it came to pass, [that] as many as came to the place where Asahel fell down and died stood still.
