Luke 11:15-18 New International Version (NIV)

15. But some of them said, “By Beelzebul, the prince of demons, he is driving out demons.”

16. Others tested him by asking for a sign from heaven.

17. Jesus knew their thoughts and said to them: “Any kingdom divided against itself will be ruined, and a house divided against itself will fall.

18. If Satan is divided against himself, how can his kingdom stand? I say this because you claim that I drive out demons by Beelzebul.
