In the New Testament Jesus performed one of his miracles at the site of the Kursi Beach dig.
It is reported slightly differently in three of the gospels:
Mark 5:1-20New American Standard Bible (NASB)
The Gerasene Demoniac
5 They came to the other side of the sea, into the country of the Gerasenes. 2 When He got out of the boat, immediately a man from the tombs with an unclean spirit met Him,3 and he had his dwelling among the tombs. And no one was able to bind him anymore, even with a chain; 4 because he had often been bound with shackles and chains, and the chains had been torn apart by him and the shackles broken in pieces, and no one was strong enough to subdue him. 5 Constantly, night and day, he was screaming among the tombs and in the mountains, and gashing himself with stones. 6 Seeing Jesus from a distance, he ran up and bowed down before Him; 7 and shouting with a loud voice, he *said, “[a]What business do we have with each other, Jesus, Son of the Most High God? I implore You by God, do not torment me!” 8 For He had been saying to him, “Come out of the man, you unclean spirit!” 9 And He was asking him, “What is your name?” And he *said to Him, “My name is Legion; for we are many.” 10 And he began to implore Him earnestly not to send them out of the country. 11 Now there was a large herd of swine feeding [b]nearby on the mountain. 12 The demons implored Him, saying, “Send us into the swine so that we may enter them.” 13 Jesus gave them permission. And coming out, the unclean spirits entered the swine; and the herd rushed down the steep bank into the sea, about two thousand of them; and they were drowned in the sea.
14 Their herdsmen ran away and reported it in the city and in the country. And the peoplecame to see what it was that had happened. 15 They *came to Jesus and *observed the man who had been demon-possessed sitting down, clothed and in his right mind, the very man who had had the “legion”; and they became frightened. 16 Those who had seen it described to them how it had happened to the demon-possessed man, and all about the swine. 17 And they began to implore Him to leave their region. 18 As He was getting into the boat, the man who had been demon-possessed was imploring Him that he might [accompany Him. 19 And He did not let him, but He *said to him, “Go home to your people and report to them what great things the Lord has done for you, and how He had mercy on you.” 20 And he went away and began to proclaim in Decapolis what great things Jesus had done for him; and everyone was amazed.
Matthew 8:28-34New American Standard Bible (NASB)
Jesus Casts Out Demons
28 When He came to the other side into the country of the Gadarenes, two men who were demon-possessed met Him as they were coming out of the tombs. They were so extremely violent that no one could pass by that way. 29 And they cried out, saying, “[a]What business do we have with each other, Son of God? Have You come here to torment us before [b]the time?” 30 Now there was a herd of many swine feeding at a distance from them. 31 The demons began to entreat Him, saying, “If You are going to cast us out, send us into the herd of swine.” 32 And He said to them, “Go!” And they came out and went into the swine, and the whole herd rushed down the steep bank into the sea and perished in the waters. 33 The herdsmen ran away, and went to the city and reported everything, [c]including what had happened to the demoniacs. 34 And behold, the whole city came out to meet Jesus; and when they saw Him, they implored Him to leave their region.
Luke 8:26-39New Revised Standard Version (NRSV)
Jesus Heals the Gerasene Demoniac
26 Then they arrived at the country of the Gerasenes,[a] which is opposite Galilee. 27 As he stepped out on land, a man of the city who had demons met him. For a long time he had worn[b] no clothes, and he did not live in a house but in the tombs. 28 When he saw Jesus, he fell down before him and shouted at the top of his voice, “What have you to do with me, Jesus, Son of the Most High God? I beg you, do not torment me”— 29 for Jesus[c] had commanded the unclean spirit to come out of the man. (For many times it had seized him; 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 wilds.) 30 Jesus then asked him, “What is your name?” He said, “Legion”; for many demons had entered him. 31 They begged him not to order them to go back into the abyss.
32 Now there on the hillside a large herd of swine was feeding; and the demons[d] begged Jesus[e] to let them enter these. So he gave them permission. 33 Then the demons came out of the man and entered the swine, and the herd rushed down the steep bank into the lake and was drowned.
34 When the swineherds saw what had happened, they ran off and told it in the city and in the country. 35 Then people came out to see what had happened, and when they came to Jesus, they found the man from whom the demons had gone sitting at the feet of Jesus, clothed and in his right mind. And they were afraid. 36 Those who had seen it told them how the one who had been possessed by demons had been healed. 37 Then all the people of the surrounding country of the Gerasenes[f] asked Jesus[g] to leave them; for they were seized with great fear. So he got into the boat and returned. 38 The man from whom the demons had gone begged that he might be with him; but Jesus[h] sent him away, saying, 39 “Return to your home, and declare how much God has done for you.” So he went away, proclaiming throughout the city how much Jesus had done for him.
