Mark 5:12-15

12And all the demons besought him, saying, Send us into the swine, that we may enter into them.

13And immediately Jesus gave them leave. And the unclean spirits went out, and entered into the swine: and the herd ran violently down a steep place into the sea, (they were about two thousand;) and were choked in the sea.

14And they that fed the swine fled, and told it in the city, and in the country. And they went out to see what it was that was done.

15And they come to Jesus, and see him that was possessed with the demon, and had the legion, sitting, and clothed, and in his right mind: and they were afraid.
