Luke 11:15-19

15But some from among them said, By Beelzebub the prince of the demons casts he out demons.

16And others tempting [him] sought from him a sign out of heaven.

17But he, knowing their thoughts, said to them, Every kingdom divided against itself is brought to desolation: and a house set against a house falls;

18and if also Satan is divided against himself, how shall his kingdom subsist? because ye say that I cast out demons by Beelzebub.

19But if I by Beelzebub cast out demons, your sons — by whom do they cast [them] out? For this reason they shall be your judges.
