2 Samuel 2:12-17

12Abner son of Ner, together with the men of Ish-Bosheth son of Saul, left Mahanaim and went to Gibeon.

13Joab son of Zeruiah and David’s men went out and met them at the pool of Gibeon. One group sat down on one side of the pool and one group on the other side.

14Then Abner said to Joab, “Let’s have some of the young men get up and fight hand to hand in front of us.” “All right, let them do it,” Joab said. 15So they stood up and were counted off—twelve men for Benjamin and Ish-Bosheth son of Saul, and twelve for David.

16Then each man grabbed his opponent by the head and thrust his dagger into his opponent’s side, and they fell down together. So that place in Gibeon was called Helkath Hazzurim. Helkath Hazzurim means field of daggers or field of hostilities.

17The battle that day was very fierce, and Abner and the Israelites were defeated by David’s men.
