Mark 5:12-15

12So all the demons begged Him, saying, “Send us to the swine, that we may enter them.”

13And at once Jesus gave them permission. Then the unclean spirits went out and entered the swine (there were about two thousand); and the herd ran violently down the steep place into the sea, and drowned in the sea.

14So those who fed the swine fled, and they told it in the city and in the country. And they went out to see what it was that had happened.

15Then they came to Jesus, and saw the one who had been demon-possessed and had the legion, sitting and clothed and in his right mind. And they were afraid.
