At that time, when Jesus came to the other side, to the country of the Gadarenes, two demoniacs met him, coming out of the tombs, so fierce that no one could pass that way. And behold, they cried out, “What have you to do with us, O Son of God? Have you come here to torment us before the time?” Now a herd of many swine was feeding at some distance from them. And the demons begged him, “If you cast us out, send us away into the herd of swine.” And he said to them, “Go.” So they came out and went into the swine; and behold, the whole herd rushed down the steep bank into the sea, and perished in the waters. The herdsmen fled, and going into the city they told everything, and what had happened to the demoniacs. And behold, all the city came out to meet Jesus; and when they saw him, they begged him to leave their neighborhood. And getting into a boat he crossed over and came to his own city. (Matthew 8:28-9:1)
A totally modern commentary on the exorcism of the legion of demons says:
“Jesus asked the man his name, and he replied, ‘Legion,’ the same word for a division of Roman soldiers. Scholars note that a legion consisted of around two thousand troops, and there would have been several legions around the Decapolis. It’s interesting that in the story, the demons beg to stay in the area. Nearby was a ‘band’ of pigs, band being the same word used for a group of military cadets (and no, we aren’t suggesting it’s okay to call police officers ‘pigs’). The demons asked to be sent among the pigs, another symbol of uncleanliness. (Jews did not touch pigs.) Jesus invited the Legion to enter the pigs. And the pigs, specifically numbered at two thousand, ‘charged’ into the sea to their deaths. And none of the listeners could have missed the subversive poetry, remembering the legion of Pharaoh’s army that charged into the sea, where they were swallowed up and drowned (Exodus 14).
[Footnote: The pig was also the mascot of Rome’s Tenth Fretensis Legion stationed in Antioch (Carter, Matthew and Empire, 71) It’s interesting to note the places where Jesus drove demons out of people: often in the temple and in the militarized zones. The words ‘come out’ that usually accompany an exorcism are the same words with which Jesus exorcized the temple, calling the money changers to ‘come out’ because they had made a market of God’s temple and marginalized visiting Gentiles.” (Shane Claiborne and Chris Haw, Jesus for President, pg.115)
