Luke 11:14-15

14One day, Jesus was telling a bad spirit to go out of a man. Because of the bad spirit, the man could not speak. But after it had gone out of him, the man could speak again. All the people that were watching were surprised at this.

15But some people in the crowd were not happy with Jesus and they said, ‘This man can send bad spirits out of people because Beelzebul gives him authority. That is Satan, the one who rules all the bad spirits.’
