Luke 8:26-33 (KJV 1900)
26 And they arrived at the country of the Gadarenes, which is over against Galilee. 27 And when he went forth to land, there met him out of the city a certain man, which had devils long time, and ware no clothes, neither abode in any house, but in the tombs. 28 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 God most high? I beseech thee, torment me not. 29 (For he had commanded the unclean spirit to come out of the man. For oftentimes it had caught him: and he was kept bound with chains and in fetters; and he brake the bands, and was driven of the devil into the wilderness.) 30 And Jesus asked him, saying, What is thy name? And he said, Legion: because many devils were entered into him. 31 And they besought him that he would not command them to go out into the deep. 32 And there was there an 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. 33 Then went the devils out of the man, and entered into the swine: and the herd ran violently down a steep place into the lake, and were choked.
Luke 9:37-42 (KJV 1900)
37 And it came to pass, that on the next day, when they were come down from the hill, much people met him. 38 And, behold, a man of the company cried out, saying, Master, I beseech thee, look upon my son: for he is mine only child. 39 And, lo, a spirit taketh him, and he suddenly crieth out; and it teareth him that he foameth again, and bruising him hardly departeth from him. 40 And I besought thy disciples to cast him out; and they could not. 41 And Jesus answering said, O faithless and perverse generation, how long shall I be with you, and suffer you? Bring thy son hither. 42 And as he was yet a coming, the devil threw him down, and tare him. And Jesus rebuked the unclean spirit, and healed the child, and delivered him again to his father.
