Mark 5:11-14

11Now there was a large herd of pigs grazing there on the mountain.

12And the demons begged Him, saying, “Send us to the pigs so that we may go into them!”

13Jesus gave them permission. And the unclean spirits came out [of the man] and entered the pigs. The herd, numbering about two thousand, rushed down the steep bank into the sea; and they were drowned [one after the other] in the sea.

14The herdsmen [tending the pigs] ran away and reported it in the city and in the country. And the people came to see what had happened.
