Luke 8:30-33

30“What is your name?” Jesus asked him. “Legion,” he said, because many demons had entered him.

31And they begged him not to banish them to the abyss.

32A large herd of pigs was there, feeding on the hillside. The demons begged him to permit them to enter the pigs, and he gave them permission.

33The demons came out of the man and entered the pigs, and the herd rushed down the steep bank into the lake and drowned.
