Matthew 8:29-34

29 Suddenly they shouted, "What have you to do with us, Son of God? Have you come here to torment us before the time?"
30 Now a large herd of swine was feeding at some distance from them.
31 The demons begged him, "If you cast us out, send us into the herd of swine."
32 And he said to them, "Go!" So they came out and entered the swine; and suddenly, the whole herd rushed down the steep bank into the sea and perished in the water.
33 The swineherds ran off, and on going into the town, they told the whole story about what had happened to the demoniacs.
34 Then the whole town came out to meet Jesus; and when they saw him, they begged him to leave their neighborhood.
