2 Samuel 2:9-12

9And he made him king over 1Gilead, over the 2Ashurites, over 3Jezreel, 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 4the 5time 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 6Gibeon with the servants of Ish-bosheth the son of Saul.
