2 Samuel 2:15-18 English Standard Version (ESV)

15. Then they arose and passed over by number, twelve for Benjamin and Ish-bosheth the son of Saul, and twelve of the servants of David.

16. And each caught 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 at Gibeon.

17. And the battle was very fierce that day. And Abner and the men of Israel were beaten before the servants of David.

18. And the three sons of Zeruiah were there, Joab, Abishai, and Asahel. Now Asahel was as swift of foot as a wild gazelle.
