Mark 5:9-13

Then Jesus asked him, “What is your name?” “My name is Legion,” he replied, “for we are many.” And he begged Jesus again and again not to send them out of the area. A large herd of pigs was feeding on the nearby hillside. The demons begged Jesus, “Send us among the pigs; allow us to go into them.” He gave them permission, and the impure spirits came out and went into the pigs. The herd, about two thousand in number, rushed down the steep bank into the lake and were drowned.
