Luke 11:15-19

But some of them said, “He casts out the demons by Beelzebul, the ruler of the demons.”

Others, to test Him, were demanding of Him a sign from heaven.

But He knew their thoughts and said to them, “Every kingdom divided against itself is laid waste; and a house divided against itself falls.

And if Satan also has been divided against himself, how will his kingdom stand? For you claim that I cast out the demons by Beelzebul.

Yet if by Beelzebul I cast out the demons, by whom do your sons cast them out? Therefore, they will be your judges.
