Luke 11:22-26

but when one stronger than he attacks him and overcomes him, he takes away his armor in which he trusted and divides his spoil. Whoever is not with me is against me, and whoever does not gather with me scatters. “When the unclean spirit has gone out of a person, it passes through waterless places seeking rest, and finding none it says, ‘I will return to my house from which I came.’ And when it comes, it finds the house swept and put in order. Then it goes and brings seven other spirits more evil than itself, and they enter and dwell there. And the last state of that person is worse than the first.”
