15-16 So they lined up for the fight, twelve Benjaminites from the side of Ish-Bosheth son of Saul, and twelve soldiers from David’s side. The men from each side grabbed their opponents’ heads and stabbed them with their daggers. They all fell dead—the whole bunch together. So, they called the place Slaughter Park. It’s right there at Gibeon.
15 Therefore, they rose up and crossed over, twelve in number of Benjamin, from the side of Ishbosheth, the son of Saul, and twelve of the youths of David.
In the meantime, Abner son of Ner, commander of Saul’s army, had taken Saul’s son Ish-Bosheth to Mahanaim and made him king over Gilead, over Asher, over Jezreel, over Ephraim, over Benjamin—king, as it turns out, over all Israel. Ish-Bosheth, Saul’s son, was forty years old when he was made king over Israel. He lasted only two years. But the people of Judah stuck with David. David ruled the people of Judah from Hebron for seven and a half years.
