2 Samuel 2:8-14

8But Abner son of Ner, the commander of Saul’s army, had already gone to Mahanaim with Saul’s son Ishbosheth.

9There he proclaimed Ishbosheth king over Gilead, Jezreel, Ephraim, Benjamin, the land of the Ashurites, and all the rest of Israel.

10Ishbosheth, Saul’s son, was forty years old when he became king, and he ruled from Mahanaim for two years. Meanwhile, the people of Judah remained loyal to David.

11David made Hebron his capital, and he ruled as king of Judah for seven and a half years.

12One day Abner led Ishbosheth’s troops from Mahanaim to Gibeon.

13About the same time, Joab son of Zeruiah led David’s troops out and met them at the pool of Gibeon. The two groups sat down there, facing each other from opposite sides of the pool.

14Then Abner suggested to Joab, “Let’s have a few of our warriors fight hand to hand here in front of us.” “All right,” Joab agreed.
