Luke 8:30-34

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

And they were begging Him not to command them to go away into the abyss.

Now there was a herd of many pigs feeding there on the mountain; and the demons begged Him to permit them to enter the pigs. And He gave them permission.

And the demons came out of the man and entered the pigs; and the herd rushed down the steep bank into the lake and was drowned.

Now when the herdsmen saw what had happened, they ran away and reported everything in the city, and in the country.
