Luke 11:15-20

15But some of them said, “He casts out demons by Beelzebub, the ruler of the demons.”

16Others, testing Him, sought from Him a sign from heaven.

17But He, knowing their thoughts, said to them: “Every kingdom divided against itself is brought to desolation, and a house divided against a house falls.

18If Satan also is divided against himself, how will his kingdom stand? Because you say I cast out demons by Beelzebub.

19And if I cast out demons by Beelzebub, by whom do your sons cast them out? Therefore they will be your judges.

20But if I cast out demons with the finger of God, surely the kingdom of God has come upon you.
