Matthew 8:30-32

8:30 And there was a good way off from them an herd of many swine feeding. 8:31 So the devils besought him, saying, If thou cast us out, suffer us to go away into the herd of swine. 8:32 And 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.
