They came to the other side of the sea, the country of the Gerasenes. And when Jesus had stepped out of the boat, immediately there met him out of the tombs a man with an unclean spirit. He lived among the tombs. And no one could bind him any more, not even with a chain, for he had often been bound with shackles and chains, but he wrenched the chains apart, and he broke the shackles in pieces. No one had the strength to subdue him. Night and day among the tombs and on the mountains he was always crying out and cutting himself with stones. And when he saw Jesus from afar, he ran and fell down before him. And crying out with a loud voice, he said, “What have you to do with me , Jesus, Son of the Most High God? I adjure you by God, do not torment me.” For he was saying to him, “Come out of the man, you unclean spirit!” And Jesus asked him, “What is your name?” He replied, “My name is Legion, for we are many.” And he begged him earnestly not to send them out of the country. Now a great herd of pigs was feeding there on the hillside, and they begged him, saying, “Send us to the pigs, let us enter them.” So he gave them permission. And the unclean spirits came out, and entered the pigs, and the herd, numbering about two thousand, rushed down the steep bank into the sea and were drowned in the sea.
A violent naked man possessed by demons confronted Yeshu. But unclean spirits cannot remain in the presence and power of the matchless goodness of God, so in fear they sought another place to work their evil.
Footnote: Jewish people did not keep pigs, like their eastern neighbors the Gerasenes, because for Jews to eat pig meat brought very bad demerit.
