Mark 5:12

10He begged him much that he would not send them away out of the country.

11Now on the mountainside there was a great herd of pigs feeding.

12All the demons begged him, saying, “Send us into the pigs, that we may enter into them.”

13At once Jesus gave them permission. The unclean spirits came out and entered into the pigs. The herd of about two thousand rushed down the steep bank into the sea, and they were drowned in the sea.

14Those who fed the pigs fled, and told it in the city and in the country. The people came to see what it was that had happened.
