Luke 8:31-33

31And they begged Jesus repeatedly not to order them to go into the Abyss. 32A large herd of pigs was feeding there on the hillside. The demons begged Jesus to let them go into the pigs, and he gave them permission.

33When the demons came out of the man, they went into the pigs, and the herd rushed down the steep bank into the lake and was drowned.
