Matthew 8:31

29And, behold, they cried out, saying, What have we to do with thee, Jesus, thou Son of God? art thou come hither to torment us before the time?

30And there was a good way off from them an herd of many swine feeding.

31So the devils besought him, saying, If thou cast us out, suffer us to go away into the herd of swine.

32And he said unto them, Go. And when they were come out, they went into the herd of swine: and, behold, the whole herd of swine ran violently down a steep place into the sea, and perished in the waters.

33And they that kept them fled, and went their ways into the city, and told every thing, and what was befallen to the possessed of the devils.
