Relative (either uncle or cousin) of King Saul of Israel, as well as Saul's chief general. The Biblical account in 1-2 Samuel seems to imply high respect for his abilities, but what little we know of his military results seems less than impressive. He could not save Saul at the Battle of Mt. Gilboa, and after that battle, with the resources of Israel at his disposal, he could not defeat the smaller, weaker armies of David. After Saul's death, he set up that king's son Ishbaal (Ish-Bosheth) as King of Israel, but then began to negotiate with David. He was killed by David's general Joab because Abner had earlier killed Joab's brother Asahel.
