2 Samuel 2:14-18

Then Abner said to Joab, “Now have the young men arise and hold a martial skills match in our presence.” And Joab said, “Have them arise!”

So they got up and went over by count, twelve for Benjamin and Ish-bosheth the son of Saul, and twelve from the servants of David.

And each one of them seized his opponent by the head and thrust his sword in his opponent’s side; so they fell down together. Therefore that place was called Helkath-hazzurim, which is in Gibeon.

That day the battle was very severe, and Abner and the men of Israel were defeated by the servants of David.

Now the three sons of Zeruiah were there, Joab, Abishai, and Asahel; and Asahel was as swift-footed as one of the gazelles that is in the field.
