Luke 11:26

26 So the bad spirit goes out and it brings back seven other spirits. They are even worse than itself. They all go into the person and they live there. Now the person's life is even worse than it was before.’

11:26When the Jewish leaders commanded a bad spirit to leave a person, it often came out. But later it went back to live inside the person again. Because the Holy Spirit did not fill him, there was room for bad spirits to come in.
