Luke 8:32-36

And there was there an herd of many swine feeding on the mountain: and they besought him that he would suffer them to enter into them. And he suffered them.

Then went the devils out of the man, and entered into the swine: and the herd ran violently down a steep place into the lake, and were choked.

When they that fed them saw what was done, they fled, and went and told it in the city and in the country.

Then they went out to see what was done; and came to Jesus, and found the man, out of whom the devils were departed, sitting at the feet of Jesus, clothed, and in his right mind: and they were afraid.

They also which saw it told them by what means he that was possessed of the devils was healed.
