Luke 11:15

11:15 But some of them said, “By the power of Beelzebul, the ruler of demons, he casts out demons.”

Luke 11:18-19

11:18 So if Satan too is divided against himself, how will his kingdom stand? I ask you this because you claim that I cast out demons by Beelzebul. 11:19 Now if I cast out demons by Beelzebul, by whom do your sons cast them out? Therefore they will be your judges.
