A locality mentioned in three passages of the Old Testament, all of which may refer to the same place. In 1 Samuel 22:19 it is referred to as a city of priests; presumably Yahweh's priests had fled there with the ephod after the capture of the ark and the destruction of Shiloah (1 Samuel 4:11). David visited Nob after he had escaped from Saul when Ahimelech was priest there and ate holy bread (1 Samuel 21:6). When Saul heard that the priest of Nob had assisted the fugitive David he raided the shrine and had Ahimelech, along with eighty-five other priests, put to death (1 Samuel 22:9, 11, 18-19).
Isaiah prophesied that the Assyrian invaders would reach Nob, between Anathoth, 4 kilometers northeast of Jerusalem, and the capital (Isaiah 10:32). [Tyndale House, The Illustrated Bible Dictionary, Vol. 2, p. 1093]
