Luke 8:28-32

²⁸And when he saw Jesus, he fell down before him; and crying out with a loud voice, he said: What have I to do with thee, Jesus, Son of the most high God? I beseech thee, do not torment me.

²⁹For he commanded the unclean spirit to go out of the man. For many times it seized him, and he was bound with chains, and kept in fetters; and breaking the bonds, he was driven by the devil into the deserts.

³⁰And Jesus asked him, saying: What is thy name? But he said: Legion; because many devils were entered into him.

³¹And they besought him that he would not command them to go into the abyss.

³²And there was there a 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.
