'Pigs' in the Bible

Now there was a great herd of pigs in that place, getting food on the mountain: and the evil spirits made a request to him that he would let them go into the pigs, and he let them.

And the evil spirits came out of the man and went into the pigs: and the herd went rushing down a sharp slope into the water and came to destruction.

And he went and put himself into the hands of one of the people of that country, and he sent him into his fields to give the pigs their food.

And so great was his need that he would have been glad to take the pigs' food, and no one gave him anything.
