Luke 11:15-19

15but some of them said, “It is by Beelzebul,1 the prince of the demons, that He drives out demons.” 16And others tested Him by demanding a sign from heaven.

17Knowing their thoughts, Jesus said to them, “Every kingdom divided against itself will be laid waste, and a house divided against a house will fall. 18If Satan is divided against himself, how can his kingdom stand? After all, you say that I drive out demons by Beelzebul. 19And if I drive out demons by Beelzebul, by whom do your sons drive them out? So then, they will be your judges.
