2 Samuel 2:8-14

8Now Abner son of Ner, Saul’s army commander, had taken Saul’s son Ish-bosheth, and brought him over to Mahanaim.

9Then he made him king over Gilead, Asher, Jezreel, Ephraim, and Benjamin—over all Israel.

10Saul’s son Ish-bosheth was 40 years old when he began to reign over Israel, and he reigned for two years. But the house of Judah followed David.

11The time that David was king in Hebron over the house of Judah was seven years and six months.

12Once Abner son of Ner and the troops of Saul’s son Ish-bosheth went out from Mahanaim to Gibeon.

13Meanwhile Joab son of Zeruiah and the troops of David went out—they met each other by the pool of Gibeon, so they sat down, one group on one side of the pool, and the other on the other side of the pool.

14Then Abner said to Joab, “Now let the young men get up and compete before us.” “Let them get up,” Joab replied.
