Luke 8:30-34

And Jesus asked him, saying, What is thy name? And he said, Legion: because many devils were entered into him.

And they besought him that he would not command them to go out into the deep.

And there was there an herd of many swine feeding on the mountain: and they besought him that he would suffer them to enter into them. And he suffered them.

Then went the devils out of the man, and entered into the swine: and the herd ran violently down a steep place into the lake, and were choked.

When they that fed them saw what was done, they fled, and went and told it in the city and in the country.
