'Pigs' in the Bible

Do not give what is holy to dogs or throw your pearls before pigs; otherwise they will trample them under their feet and turn around and tear you to pieces.

A large herd of pigs was feeding some distance from them.

Then the demons begged him, "If you drive us out, send us into the herd of pigs."

And he said, "Go!" So they came out and went into the pigs, and the herd rushed down the steep slope into the lake and drowned in the water.
