Beelzebub (be-ĕl'ze-bŭb), lord of filth, or of flies. A name of contempt applied to Satan, the prince of the evil angels. Beelzebub, in the original Greek, is, in every instance, "Beelzebul." See margin of Revised Version. This name is not so much a contemptuous corruption of Baalzebub, the god of Ekron, as it is a designation of idols; hence Beelzebul = the idol of idols, i.e., the chief abomination, was used as an appellation of the prince of devils. Matthew 10:25, Matthew 12:24, Matthew 12:27, Mark 3:22, Luke 1:11-27.
