'Pigs' in the Bible

Don’t give what is holy to dogs or toss your pearls before pigs, or they will trample them with their feet, turn, and tear you to pieces.

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

“If You drive us out,” the demons begged Him, “send us into the herd of pigs.”

“Go!” He told them. So when they had come out, they entered the pigs. And suddenly the whole herd rushed down the steep bank into the sea and perished in the water.
