Now when Saul saw David going out to meet the Philistine, he said to Abner, the commander of the army, Abner, whose son is this youth? And Abner said, As your soul lives, O king, I do not know.

But Abner the son of Ner, commander of Saul's army, took Ishbosheth the son of Saul and brought him over to Mahanaim;

And when Abner had returned to Hebron, Joab took him aside in the gate to speak with him privately, and there stabbed him in the stomach, so that he died for the blood of Asahel his brother.
