1. Nephew of David, and one of his captains
And there were three sons of Zeruiah there, Joab, and Abishai, and Asahel: and Asahel was as light of foot as a wild roe. And Asahel pursued after Abner; and in going he turned not to the right hand nor to the left from following Abner. Then Abner looked behind him, and said, Art thou Asahel? And he answered, I am. And Abner said to him, Turn thee aside to thy right hand or to thy left, and lay thee hold on one of the young men, and take thee his armor. But Asahel would not turn aside from following of him. And Abner said again to Asahel, Turn thee aside from following me: wherefore should I smite thee to the ground? how then should I hold up my face to Joab thy brother? 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. Joab also and Abishai pursued after Abner: and the sun went down when they were come to the hill of Ammah, that lieth before Giah by the way of the wilderness of Gibeon. (2 Samuel 2:18-2418And there were three sons of Zeruiah there, Joab, and Abishai, and Asahel: and Asahel was as light of foot as a wild roe. 19And Asahel pursued after Abner; and in going he turned not to the right hand nor to the left from following Abner. 20Then Abner looked behind him, and said, Art thou Asahel? And he answered, I am. 21And Abner said to him, Turn thee aside to thy right hand or to thy left, and lay thee hold on one of the young men, and take thee his armor. But Asahel would not turn aside from following of him. 22And Abner said again to Asahel, Turn thee aside from following me: wherefore should I smite thee to the ground? how then should I hold up my face to Joab thy brother? 23Howbeit 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. 24Joab also and Abishai pursued after Abner: and the sun went down when they were come to the hill of Ammah, that lieth before Giah by the way of the wilderness of Gibeon. (2 Samuel 2:18‑24))
