'Pigs' in the Bible

Do not give that which is holy to the dogs, or put your jewels before pigs, for fear that they will be crushed under foot by the pigs whose attack will then be made against you.

Now there was, some distance away, a great herd of pigs taking their food.

And the evil spirits made strong prayers to him, saying, If you send us out, let us go into the herd of pigs.

And he said to them, Go. And they came out, and went into the pigs; and the herd went rushing down a sharp slope into the sea and came to their end in the water.
