Mark 5:9-13

Then Jesus asked him, “What is your name?” He answered, “My name is Legion, because we are many spirits.” He begged Jesus again and again not to send them out of that area. A large herd of pigs was feeding on a hill near there. The demons begged Jesus, “Send us into the pigs; let us go into them.” So Jesus allowed them to do this. The evil spirits left the man and went into the pigs. Then the herd of pigs—about two thousand of them—rushed down the hill into the lake and were drowned.
