15Then there arose and went over by number twelve of Benjamin, which pertained to Ishbosheth the son of Saul, and twelve of the servants of David. 16And they caught every one his fellow by the head, and thrust his sword in his fellow's side; so they fell down together: wherefore that place was called Helkathhazzurim, which is in Gibeon. 17And there was a very sore battle that day; and Abner was beaten, and the men of Israel, before the servants of David. 18And 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 armour. But Asahel would not turn aside from following of him.
