Mark 5:11

7 And he shouted in a loud voice, “What do You want with me, Jesus, Son of the Most High God? I beg You before God not to torture me!”

8 For Jesus had already declared, “Come out of this man, you unclean spirit!”

9 “What is your name?” Jesus asked. “My name is Legion,” he replied, “for we are many.”

10 And he begged Jesus repeatedly not to send them out of that region.

11 There on the nearby hillside a large herd of pigs was feeding.

12 So the demons begged Jesus, “Send us to the pigs, so that we may enter them.”

13 He gave them permission, and the unclean spirits came out and went into the pigs, and the herd of about two thousand rushed down the steep bank into the sea and drowned in the water.

14 Those tending the pigs ran off and reported this in the town and countryside, and the people went out to see what had happened.

15 When they came to Jesus, they saw the man who had been possessed by the legion of demons sitting there, clothed and in his right mind; and they were afraid.
