Luke 8:28-32

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. Now there was there a herd of many swine feeding on the mountain: and they entreated him that he would give them leave to enter into them. And he gave them leave.
