Mark 5:11-13

11Now there was there just at the mountain a great herd of swine feeding;

12and they besought him, saying, Send us into the swine that we may enter into them.

13And Jesus [immediately] allowed them. And the unclean spirits going out entered into the swine, and the herd rushed down the steep slope, into the sea (about two thousand), and were choked in the sea.
