Mark 5:12

9 And Jesus said, What is your name? And he made answer, My name is Legion, because there are a great number of us.

10 And he made strong prayers to him not to send them away out of the country.

11 Now on the mountain side there was a great herd of pigs getting their food.

12 And they said to him, Send us into the pigs, so that we may go into them.

13 And he let them do it. And the unclean spirits came out and went into the pigs; and the herd went rushing down a sharp slope into the sea, about two thousand of them; and they came to their death in the sea.

14 And their keepers went running and gave an account of it in the town and in the country. And people came to see what had taken place.

15 And they came to Jesus, and saw the man in whom had been the evil spirits seated, clothed and with full use of his senses, and they were full of fear.
