Soon after Saul and Jonathan died in battle against the Philistines, Abner son of Ner, Saul's army commander, had taken Ish-bosheth son of Saul and brought him across to Mahanaim and made him king over Gilead, the Ashurites, Jezreel, Ephraim, and Benjamin [and] over all Israel (II Sam.
The Bible relates that Ish-bosheth son of Saul was forty years old when he became king of Israel, and he reigned two years.
If, after the death of Saul, Ish-bosheth sat on the throne of Israel and his kingdom lasted for two years, but at the same point in time David had reigned over Judah for seven years and six months, this strongly suggests that David had conquered the southern kingdom of Judah five and a half years before Ishbosheth ascended the throne of Israel, and, most likely, five and a half years before Saul's death.

David also sent messengers to Ish-bosheth son of Saul, to say, "Give me my wife Michal, for whom I paid the bride-price of one hundred Philistine foreskins" (II Sam.
When addressing Ish-bosheth, David referred to my wife Michal, since he wanted to emphasize his legal marriage to Michal so that Ish-bosheth would be responsive.
The Bible tells of the protracted struggle for the throne that ensues after the death of Saul, between his son Ish-bosheth and David (II Sam.
