Nob (high place) (1 Samuel 22:19; Nehemiah 11:32) a sacerdotal city in the tribe of Benjamin and situated on some eminence near Jerusalem. It was one of the places where the ark of Jehovah was kept for a time during the days of its wanderings. (2 Samuel 6:1) etc. but the event for which Nob was most noted in the Scripture annals was a frightful massacre which occurred there in the reign of Saul. (1 Samuel 22:17-19)
