When Jesus drove out a demon, some who watched explained it away. In Matthew 12:24 the Pharisees say, “This fellow doth not cast out devils, but by Beelzebub the prince of the devils,” and the scribes in Mark 3:22 say much the same. Jesus answers with a question of his own, asking by whom their own followers cast them out. Elsewhere he notes that if the master of the house was called Beelzebub, his household should expect the same. Read Matthew 12:22 through 30 for the full exchange.

It is enough for the disciple that he be as his master, and the servant as his lord. If they have called the master of the house Beelzebub, how much more shall they call them of his household?
But when the Pharisees heard it, they said, This fellow doth not cast out devils, but by Beelzebub the prince of the devils.
And if I by Beelzebub cast out devils, by whom do your children cast them out? therefore they shall be your judges.
And the scribes which came down from Jerusalem said, He hath Beelzebub, and by the prince of the devils casteth he out devils.
Matthew George Easton, 1897
(Gr. form Beel’zebul), the name given to Satan, and found only in the New Testament (Matt. 10:25; 12:24, 27; Mark 3:22). It is probably the same as Baalzebub (q.v.), the god of Ekron, meaning “the lord of flies,” or, as others think, “the lord of dung,” or “the dung-god.”
