Matthew 8:28-32

28And there met him, when he came to the other side, to the country of the Gergesenes, two possessed by demons, coming out of the tombs, exceeding dangerous, so that no one was able to pass by that way.

29And behold, they cried out, saying, What have we to do with thee, Son of 1God? hast thou come here before the time to torment us?

30Now there was, a great way off from them, a herd of many swine feeding;

31and the demons besought him, saying, If thou cast us out, send us away into the herd of swine.

32And he said to them, Go. And they, going out, departed into the herd of swine; and lo, the whole herd [of swine] rushed down the steep slope into the sea, and died in the waters.
