Mark 5:12-16

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

And forthwith 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.

And 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.

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

And they that saw it told them how it befell to him that was possessed with the devil, and also concerning the swine.
