Luke 8:29-33

For Jesus had already commanded the evil spirit to come out of him. This spirit had often taken control of the man. Even when he was placed under guard and put in chains and shackles, he simply broke them and rushed out into the wilderness, completely under the demon’s power. Jesus demanded, “What is your name?” “Legion,” he replied, for he was filled with many demons. The demons kept begging Jesus not to send them into the bottomless pit. There happened to be a large herd of pigs feeding on the hillside nearby, and the demons begged him to let them enter into the pigs. So Jesus gave them permission. Then the demons came out of the man and entered the pigs, and the entire herd plunged down the steep hillside into the lake and drowned.
