Luke 8:30-33

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

31And they began to beg him not to order them to depart into the abyss.

32Now a large herd of pigs was feeding there on the hillside, and the demonic spirits begged Jesus to let them go into them. He gave them permission.

33So the demons came out of the man and went into the pigs, and the herd of pigs rushed down the steep slope into the lake and drowned.
