Mark 5:9

And Jesus said, What is your name? And he made answer, My name is Legion, because there are a great number of us.

Matthew 26:53

Does it not seem possible to you that if I make request to my Father he will even now send me an army of angels?

Luke 8:30

And Jesus said to him, What is your name? And he said, Legion; for a number of spirits had gone into him.

Then he goes and takes with him seven other spirits worse than himself, and they go in and make it their living-place: and the last condition of that man is worse than the first. Even so will it be with this evil generation.

Mark 5:15

And they came to Jesus, and saw the man in whom had been the evil spirits seated, clothed and with full use of his senses, and they were full of fear.
