2 Samuel 2:8-17

⁸But Abner the son of Ner, commander of Saul’s army, had taken Ish-bosheth the son of Saul and brought him over to Mahanaim. ⁹And he made him king over Gilead, over the Ashurites, over Jezreel, over Ephraim, and over Benjamin, even over all Israel. ¹⁰Ish-bosheth, Saul’s son, was forty years old when he became king over Israel, and he was king for two years. The house of Judah, however, followed David. ¹¹And the time that David was king in Hebron over the house of Judah was seven years and six months.

¹²Now Abner the son of Ner, went from Mahanaim to Gibeon with the servants of Ish-bosheth the son of Saul. ¹³And Joab the son of Zeruiah and the servants of David went out and met them by the pool of Gibeon; and they sat down, Abner’s men on the one side of the pool and Joab’s men on the other side of the pool. ¹⁴Then 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!” ¹⁵So 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. ¹⁶And 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. ¹⁷That day the battle was very severe, and Abner and the men of Israel were defeated by the servants of David.
