Zebul in the Bible

Enough for the learner to be on a level with his teacher, and for the servant to be on a level with his master. If they have called the master of the house Baal-zebul, how much more will they slander his servants?

The Pharisees heard it and said, "This man only expels demons by the power of Baal-zebul, the Prince of demons."

And if it is by Baal-zebul's power that I expel the demons, by whose power do your disciples expel them? They therefore shall be your judges.
