'Pigs' in the Bible

"Do not give what is holy to dogs, or throw your pearls in front of pigs, lest they trample them with their feet, and turn around [and] tear you to pieces.

Now a long way from them a large herd of pigs was feeding.

So the demons implored him, saying, "If you are going to expel us, send us into the herd of pigs."

And he said to them, "Go!" So they departed [and] went into the pigs, and behold, the whole herd rushed headlong down the steep slope into the sea and drowned in the water.
