Abner son of Ner commanded
Saul's army and appears repeatedly during
David's rise. After Saul died, Abner installed Saul's son Ish-bosheth over much of Israel, producing conflict with David's house in Judah. A confrontation at Gibeon led to battle, during which Abner killed Joab's brother Asahel after repeatedly warning him to turn aside. Later a dispute with Ish-bosheth caused Abner to negotiate with David and promise to bring Israel under David's kingship. David received him peacefully, but Joab murdered Abner in revenge for Asahel. David publicly mourned Abner, denied complicity, and lamented that a great man had fallen in Israel.
