Luke 8:27-39

Now when Jesus stepped out on land, He was met by a man from the city [of Gerasa] who was possessed with demons. For a long time he had worn no clothes, and was not living in a house, but among the tombs. Seeing Jesus, he cried out [with a terrible voice from the depths of his throat] and fell down before Him [in dread and terror], and shouted loudly, “What business do we have [in common] with each other, Jesus, Son of the Most High God? I beg You, do not torment me [before the appointed time of judgment]!” Now He was [already] commanding the unclean spirit to come out of the man. For it had seized him [violently] many times; and he was kept under guard and bound with chains and shackles, but he would break the bonds and be driven by the demon into the desert. Then Jesus asked him, “What is your name?” And he answered, “Legion”; because many demons had entered him. They continually begged Him not to command them to go into the abyss. [Rev 9:1] Now a large herd of pigs was feeding there on the mountain. The demons begged Jesus to allow them to enter the pigs, and He gave them permission. Then the demons came out of the man and entered the pigs; and the herd rushed down the steep bank into the lake and was drowned. When the herdsmen saw what had happened, they ran away and told it in the city and out in the country. And people came out to see what had happened. They came to Jesus, and found the man from whom the demons had gone out, sitting at Jesus’ feet, clothed and in his right mind (mentally healthy); and they were frightened. Those who had seen it told them how the man who had been demon-possessed had been healed. Then all the people of the country of the Gerasenes and the surrounding district asked Him to leave them, because they were overwhelmed with fear. So Jesus got into the boat and returned [to the west side of the Sea of Galilee]. But the man from whom the demons had gone out kept begging Him, pleading to go with Him; but Jesus sent him away, saying, “Return home and tell [about] all the great things God has done for you.” So the man went away, proclaiming throughout the whole city what great things Jesus had done for him.
