Mark 5:9

5And always, night and day, he was in the mountains, and in the tombs, crying, and cutting himself with stones.

6But when he saw Jesus afar off, he ran and worshipped him,

7And cried with a loud voice, and said, What have I to do with thee, Jesus, thou Son of the most high God? I adjure thee by God, that thou torment me not.

8For he said unto him, Come out of the man, thou unclean spirit.

9And he asked him, What is thy name? And he answered, saying, My name is Legion: for we are many.

10And he besought him much that he would not send them away out of the country.

11Now there was there nigh unto the mountains a great herd of swine feeding.

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

13And 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.
