Luke 8:27-31

And when he was come forth upon the land, there met him a certain man out of the city, who had demons; and for a long time he had worn no clothes, and abode not in any house, but in the tombs. And when he saw Jesus, he cried out, and fell down before him, and with a loud voice said, What have I to do with thee, Jesus, thou Son of the Most High God? I beseech thee, torment me not. For he was commanding the unclean spirit to come out from the man. For oftentimes it had seized him: and he was kept under guard, and bound with chains and fetters; and breaking the bands asunder, he was driven of the demon into the deserts. And Jesus asked him, What is thy name? And he said, Legion; for many demons were entered into him. And they entreated him that he would not command them to depart into the abyss.
