Mark 5:9

³⁰Jesus asked him, “What is your name?” He said, “Legion,” for many demons had entered into him.

¹⁵They came to Jesus, and saw him who had been possessed by demons sitting, clothed, and in his right mind, even him who had the legion; and they were afraid.

⁵³Or do you think that I couldn’t ask my Father, and he would even now send me more than twelve legions of angels?

²¹“When the strong man, fully armed, guards his own dwelling, his goods are safe. ²²But when someone stronger attacks him and overcomes him, he takes from him his whole armor in which he trusted, and divides his plunder.

²³“He who is not with me is against me. He who doesn’t gather with me scatters.

²⁴The unclean spirit, when he has gone out of the man, passes through dry places, seeking rest; and finding none, he says, ‘I will turn back to my house from which I came out.’ ²⁵When he returns, he finds it swept and put in order. ²⁶Then he goes and takes seven other spirits more evil than himself, and they enter in and dwell there. The last state of that man becomes worse than the first.”

⁴⁵Then he goes and takes with himself seven other spirits more evil than he is, and they enter in and dwell there. The last state of that man becomes worse than the first. Even so will it be also to this evil generation.”
