2 Samuel 2:18

16They each caught his opponent by the head and thrust his sword in his fellow’s side; so they fell down together. Therefore that place in Gibeon was called Helkath Hazzurim.

17The battle was very severe that day; and Abner was beaten, and the men of Israel, before David’s servants.

18The three sons of Zeruiah were there: Joab, Abishai, and Asahel. Asahel was as light of foot as a wild gazelle.

19Asahel pursued Abner. He didn’t turn to the right hand or to the left from following Abner.

20Then Abner looked behind him and said, “Is that you, Asahel?” He answered, “It is.”
